Description

The CIa-VaI Model 100-01 Hytrol Valve is a main valve for
CIa-VaI Automatic Control Valves. It is a hydraulically operated,
diaphragm-actuated, globe or angle pattern valve.

This valve consists of three major components; body, diaphragm
assembly, and cover. The diaphragm assembly is the only
moving part. The diaphragm assembly uses a diaphragm of nylon
fabric bonded with synthetic rubber. A synthetic rubber disc,
contained on three and one half sides by a disc retainer and disc
guide, forms a seal with the valve seat when pressure is applied
above the diaphragm. The diaphragm assembly forms a sealed
chamber in the upper portion of the valve, separating operating
pressure from line pressure.

Installation

1. Before valve is installed, pipe lines should be flushed of all
chips, scale and foreign matter.

2. It is recommended that either gate or block valves be
installed on both ends of the 100-01 Hytrol Valve to facilitate
isoIating the valve for preventive maintenance and repairs.

3. Place the valve in the line with flow through the valve in the
direction indicated on the inlet nameplate. (See “Flow Direction”
Section)

4. Allow sufficient room around valve to make adjustments and
for disassembly.

5. CIa-VaI 100-01 Hytrol Valves operate with maximum effic iency
when mounted in horizontal piping with the cover UP, however,
other positions are acceptable. Due to size and weight of the
cover and internal components of 8 inch and larger valves,

installation with the cover UP is advisable. This makes internal
parts readily accessible for periodic inspection.

6. Caution must be taken in the installation of this valve to insure
that galvanic and/or electrolytic action does not take place. The
proper use of dielectric fittings and gaskets are required in all
systems using dissimilar metals.

7. If a pilot control system is installed on the 100-01 Hytrol Valve,
use care to prevent damage. If it is necessary to remove fittings
or components, be sure they are kept clean and replaced
exactly as they were.

8. After the valve is installed and the system is first pressurized,
vent air from the cover chamber and pilot system tubing by
loosening fittings at all high points.

Tight Closing Operation

When pressure from the valve inlet (or
an equivalent independent operating
pressure) is applied to the diaphragm
chamber the valve closes drip-tight.

Full Open Operation

When pressure in diaphragm chamber
is relieved to a zone of lower pressure
(usually atmosphere) the line pressure
(5 psi Min.) at the valve inlet opens the
valve.

Modulating Action

Valve modulates when diaphragm pres­sure is held at an intermediate point
between inlet and discharge pressure.
With the use of a Cla-Val. "modulating
control," which reacts to line pressure
changes, the pressure above the
diaphragm is varied, allowing the valve
to throttle and compensate for the
change.

Flow Direction

The flow through the 100-01 Hytrol Valve can be in one of two
directions. When flow is “up-and-over the seat,” it is in “normal”
flow and the valve will fail in the open position. When flow is “over­the seat-and down,” it is in “reverse” flow and the valve will fail in
the closed position. There are no permanent flow arrow markings.

The valve must be installed according to nameplate data.

Troubleshooting

The following troubleshooting information deals strictly with the
Model 100-01 Hytrol Valve. This assumes that all other compo­nents of the pilot control system have been checked out and are
in proper working condition. (See appropriate sections in
Technical Manual for complete valve).

Three Checks

The 100-01 Hytrol Valve has only one moving part (the diaphragm
and disc assembly). So, there are only three major types of prob­lems to be considered.

First: Valve is stuck - that is, the diaphragm assembly is not free
to move through a full stroke either from open to close or vice
versa.

Second: Valve is free to move and can’t close because of a worn
out diaphragm.

Third: Valve leaks even though it is free to move and the
diaphragm isn’t leaking.

Closed isolation valves in control system, or in main line.

Lack of cover chamber pressure.

Diaphragm damaged. (See Diaphragm Check.)

Diaphragm assembly inoperative.
Corrosion or excessive scale build up on valve stem.
(See Freedom of Movement Check)

Mechanical obstruction. Object lodged in valve.
(See Freedom of Movement Check)

Worn disc. (See Tight Sealing Check)

Badly scored seat. (See Tight Sealing Check)

Closed upstream and/or downstream isolation
valves in main line.

Insufficient line pressure.

Diaphragm assembly inoperative. Corrosion or excessive
buildup on valve stem. (See Freedom of Movement Check)

Diaphragm damaged. (For valves in "reverse flow" only)

After checking out probable causes and remedies, the following three checks can be used to diagnose the nature of the
problem before maintenance is started. They must be done in the order shown.

Open Isolation valves.

Check upstream pressure, pilot system, strainer, tubing, valves, or needle
valves for obstruction.

Replace diaphragm.

Clean and polish stem. Inspect and replace any damaged or badly eroded
part.

Remove obstruction.

Replace disc.

Replace seat.

Open isolation valves.

Check upstream pressure. (Minimum 5 psi flowing line pressure differential.)

Clean and polish stem. Inspect and replace any
damaged or badly eroded part.

Replace diaphragm.

Fails to Close

Fails to Open

CAUTION:
Care should be taken when doing the troubleshooting checks on
the 100-01 Hytrol Valve. These checks do require the valve to
open fully. This will either allow a high flow rate through the
valve, or the downstream pressure will quickly increase to the
inlet pressure. In some cases, this can be very harmful. Where
this is the case, and there are no block valves in the system to
protect the downstream piping, it should be realized that the
valve cannot be serviced under pressure. Steps should be
taken to remedy this situation before proceeding any further.

SYMPTOM PROBABLE CAUSE REMEDY

Recommended Tools

1. Three pressure gauges with ranges suitable to the instal­lation to be put at Hytrol inlet, outlet and cover connections.

2. Cla-Val Model X101 Valve Position Indicator. This pro­vides visual indication of valve position without disassembly
of valve.

3. Other items are: suitable hand tools such as screw­drivers, wrenches, etc. soft jawed (brass or aluminum) vise,
400 grit wet or dry sandpaper and water for cleaning.

All trouble shooting is possible without removing the valve from the
line or removing the cover. It is highly recommended to permanently
install a Model X101 Valve Position Indicator and three gauges in
unused Hytrol inlet, outlet and cover connections.

Diaphragm Check (#1 )

1. Shut off pressure to the Hytrol Valve by slowly closing upstream
and downstream isolation valves. SEE CAUTION.

2. Disconnect or close all pilot control lines to the valve cover and

leave only one fitting in highest point of cover open to atmosphere.

3.With the cover vented to atmosphere, slowly open upstream
isolation valve to allow some pressure into the Hytrol Valve body.
Observe the open cover tapping for signs of continuous flow. It is
not necessary to fully open isolating valve. Volume in cover cham­ber capacity chart will be displaced as valve moves to open posi­tion. Allow sufficient time for diaphragm assembly to shift posi­tions. If there is no continuous flow, you can be quite certain the
diaphragm is sound and the diaphragm assembly is tight. If the
fluid appears to flow continuously this is a good reason to believe
the diaphragm is either damaged or it is loose on the stem. In
either case, this is sufficient cause to remove the valve cover and
investigate the leakage. (See “Maintenance” Section for procedure.)

Freedom of Movement Check (#2)

4. Determining the Hytrol Valve’s freedom of movement can be

done by one of two methods.

5. For most valves it can be done after completing Diaphragm
Check (Steps 1, 2, and 3). SEE CAUTION. At the end of step 3
the valve should be fully open.

6. If the valve has a Cla-Val X101 Position Indicator, observe the
indicator to see that the valve opens wide. Mark the point of max­imum opening.

7. Re-connect enough of the control system to permit the appli­cation of inlet pressure to the cover. Open pilot system cock so
pressure flows from the inlet into the cover.

8. While pressure is building up in the cover, the valve should
close smoothly. There is a hesitation in every Hytrol Valve closure,
which can be mistaken for a mechanical bind. The stem will
appear to stop moving very briefly before going to the closed posi­tion. This slight pause is caused by the diaphragm flexing at a
particular point in the valve’s travel and is not caused by a
mechanical bind.

9. When closed, a mark should be made on the X101 Valve posi­tion indicator corresponding to the “closed” position. The distance
between the two marks should be approximately the stem travel
shown in chart.

10. If the stroke is different than that shown in stem travel chart
this is a good reason to believe something is mechanically restrict­ing the stroke of the valve at one end of its travel. If the flow does
not stop through the valve when in the indicated “closed” position,
the obstruction probably is between the disc and the seat. If the
flow does stop, then the obstruction is more likely in the cover. In
either case, the cover must be removed, and the obstruction locat­ed and removed. The stem should also be checked for scale build­up. (See “Maintenance, section for procedure.)

11. For valves 6” and smaller, the Hytrol Valve’s freedom of move­ment check can also be done after all pressure is removed from
the valve. SEE CAUTION. After closing inlet and outlet isolation
valves and bleeding pressure from the valve, check that the cover
chamber and the body are temporarily vented to atmosphere.
Insert fabricated tool into threaded hole in top of valve stem, and
lift the diaphragm assembly manually. Note any roughness. The
diaphragm assembly should move smoothly throughout entire
valve stroke. The tool is fabricated from rod that is threaded on
one end to fit valve stem and has a “T” bar handle of some kind
on the other end for easy gripping. (See chart in Step 4 of
“Disassembly” Section.)

12. Place marks on this diaphragm assembly lifting tool when the
valve is closed and when manually positioned open. The distance
between the two marks should be approximately the stem travel
shown in stem travel chart. If the stroke is different than that
shown, there is a good reason to believe something is mechani­cally restricting the stroke of the valve. The cover must be
removed, and the obstruction located and removed. The stem
should also be checked for scale build-up. (See “Maintenance”
Section for procedure.)

Tight Sealing Check (#3)

13. Test for seat leakage after completing checks #1 & #2 (Steps

1 to 12). SEE CAUTION. Close the isolation valve downstream of
the Hytrol Valve. Apply inlet pressure to the cover of the valve, wait
until it closes. Install a pressure gauge between the two closed
valves using one of the two ports in the outlet side of the Hytrol.
Watch the pressure gauge. If the pressure begins to climb, then
either the downstream isolation valve is permitting pressure to
creep back, or the Hytrol is allowing pressure to go through it.
Usually the pressure at the Hytrol inlet will be higher than on the
isolation valve discharge, so if the pressure goes up to the inlet
pressure, you can be sure the Hytrol is leaking. Install another
gauge downstream of isolating valve. If the pressure between the
valves only goes up to the pressure on the isolation valve
discharge, the Hytrol Valve is holding tight, and it was just the iso­lation valve leaking.

Maintenance

Preventative Maintenance

The Cla-Val Co. Model 100-01 Hytrol Valve requires no lubrication or
packing and a minimum of maintenance. However, a periodic inspec­tion schedule should be established to determine how the operating
conditions of the system are affecting the valve. The effect of these
actions must be determined by inspection.

Disassembly

Inspection or maintenance can be accomplished without removing
the valve from the line. Repair kits with new diaphragm and disc are
recommended to be on hand before work begins.

WARNING: Maintenance personnel can be injured and equipment
damaged if disassembly is attempted with pressure in the valve. SEE

CAUTION.

1. Close upstream and downstream isolation valves and independ-
ent operating pressure when used to shut off all pressure to the

valve.

2. Loosen tube fittings in the pilot system to remove pressure from
valve body and cover chamber. After pressure has been released
from the valve, use care to remove the controls and tubing. Note and
sketch position of tubing and controls for re-assembly. The schemat­ic in front of the Technical Manual can be used as a guide when
reassembling pilot system.

3. Remove cover nuts and remove cover. If the valve has been in
service for any length of time, chances are the cover will have to be
loosened by driving upward along the edge of the cover with a dull
cold chisel.

On 6” and smaller valves block and tackle or a power hoist can be
used to lift valve cover by inserting proper size eye bolt in place of
the center cover plug. on 8” and larger valves there are 4 holes (5/8”
— 11 size) where jacking screws and/or eye bolts may be inserted
for lifting purposes. Pull cover straight up to keep from damaging
the integral seat bearing and stem.

4. Remove the diaphragm and disc assembly from the valve body.
With smaller valves this can be accomplished by hand by pulling

straight up on the stem so as not to damage the seat bearing.

On large valves, an eye bolt of proper size can be installed in the
stem and the diaphragm assembly can be then lifted with a block and
tackle or power hoist. Take care not to damage the stem or bearings.
The valve won't work if these are damaged.

5. The next item to remove is the stem nut. Examine the stem
threads above the nut for signs of mineral deposits or corrosion.
If the threads are not clean, use a wire brush to remove as much
of the residue as possible. Attach a good fitting wrench to the nut
and give it a sharp “rap” rather than a steady pull. Usually
several blows are sufficient to loosen the nut for further removal.
On the smaller valves, the entire diaphragm assembly can be held
by the stem in a vise equipped with soft brass jaws before
removing the stem nut.

The use of a pipe wrench or a vise without soft brass jaws scars
the fine finish on the stem. No amount of careful dressing can
restore the stem to its original condition. Damage to the finish of
the stem can cause the stem to bind in the bearings and the valve
will not open or close.

6. After the stem nut has been removed, the diaphragm assembly
breaks down into its component parts. Removal of the disc from
the disc retainer can be a problem if the valve has been in serv­ice for a long time. Using two screwdrivers inserted along the out­side edge of the disc usually will accomplish its removal. Care
should be taken to preserve the spacer washers in water, partic­ularly if no new ones are available for re-assembly.

7. The only part left in the valve body is the seat which ordinarily
does not require removal. Careful cleaning and polishing of inside
and outside surfaces with 400 wet/dry sandpaper will usually
restore the seat’s sharp edge. If, however, it is badly worn and
replacement is necessary, it can be easily removed.

Seats in valve sizes 1 1/4” through 6” are threaded into the valve
body. They can be removed with accessory X109 Seat Removing
Tool available from the factory. On 8” and larger valves, the seat
is held in place by flat head machine screws. Use a tight-fitting,
long shank screwdriver to prevent damage to seat screws. If upon
removal of the screws the seat cannot be lifted out, it will be nec­essary to use a piece of angle or channel iron with a hole drilled
in the center. Place it across the body so a long stud can be insert­ed through the center hole in the seat and the hole in the angle
iron. By tightening the nut a uniform upward force is exerted on
the seat for removal.

NOTE: Do not lift up on the end of the angle iron as this may force
the integral bearing out of alignment, causing the stem to bind.

Lime Deposits

One of the easiest ways to remove lime deposits from the valve
stem or other metal parts is to dip them in a 5-percent muriatic
acid solution just long enough for the deposit to dissolve. This
will remove most of the common types of deposits. CAUTlON:
USE EXTREME CARE WHEN HANDLING ACID. Rinse parts in
water before handling. If the deposit is not removed by acid, then
a fine grit (400) wet or dry sandpaper can be used with water.

Reassembly

1. Reassembly is the reverse of the disassembly procedure. If a

new disc has been installed, it may require a different number of
spacer washers to obtain the right amount of “grip” on the disc.
When the diaphragm assembly has been tightened to a point
where the diaphragm cannot be twisted, the disc should be com­pressed very slightly by the disc guide. Excessive compression
should be avoided. Use just enough spacer washers to hold the
disc firmly without noticeable compression.

2. MAKE SURE THE STEM NUT IS VERY TIGHT. Attach a good
fitting wrench to the nut and give it a sharp “rap” rather than a
steady pull. Usually several blows are sufficient to tighten the
stem nut for final tightening. Failure to do so could allow the
diaphragm to pull loose and tear when subjected to pressure.

Test Procedure After Valve Assembly

There are a few simple tests which can be made in the field to
make sure the Hytrol Valve has been assembled properly. Do
these before installing pilot system and returning valve to
service. These are similar to the three troubleshooting tests.

1. Check the diaphragm assembly for freedom of movement
after all pressure is removed from the valve. SEE CAUTlON.
Insert fabricated tool into threaded hole in top of valve stem, and
lift the diaphragm assembly manually. Note any roughness,
sticking or grabbing. The diaphragm assembly should move
smoothly throughout entire valve stroke. The tool is fabricated
from rod that is threaded on one end to fit valve stem (See chart
in Step 4 of “Disassembly” section.) and has a “T” Bar handle of
some kind on the other end for easy gripping.

Place marks on this diaphragm assembly lifting tool when the
valve is closed and when manually positioned open. The dis­tance between the two marks should be approximately the stem
travel shown in stem travel chart. (See “Freedom of Movement
Check” section.) If the stroke is different than that shown, there
is a good reason to believe something is mechanically restricting
the stroke of the valve. The cover must be removed, the obstruc­tion located and removed. (See “Maintenance” Section for
procedure.)

Inspection of Parts

After the valve has been disassembled, each part should be
examined carefully for signs of wear, corrosion, or any other
abnormal condition. Usually, it is a good idea to replace the rub­ber parts (diaphragm and disc) unless they are free of signs of
wear. These are available in a repair kit. Any other parts which
appear doubtful should be replaced. WHEN ORDERlNG
PARTS, BE SURE TO GIVE COMPLETE NAMEPLATE DATA,
ITEM NUMBER AND DESCRlPTlON.

NOTE: If a new disc isn’t available, the existing disc can be
turned over, exposing the unused surface for contact with the
seat. The disc should be replaced as soon as practical.

3. Carefully install the diaphragm assembly by lowering the stem
through the seat bearing. Take care not to damage the stem or
bearing. Line up the diaphragm holes with the stud or bolt holes
on the body. on larger valves with studs, it may be necessary to
hold the diaphragm assembly up part way while putting the
diaphragm over the studs.

4. Put spring in place and replace cover. Make sure diaphragm
is Iying smooth under the cover.

5. Tighten cover nuts firmly using a cross-over pattern until all
nuts are tight.

6. Test Hytrol Valve before re-installing pilot valve system.

Due to the weight of the diaphragm assembly this procedure is
not possible on valves 8” and larger. on these valves, the same
determination can be made by carefully introducing a low
pressure-less than five psi) into the valve body with the cover
vented. SEE CAUTION. Looking in cover center hole see the
diaphragm assembly lift easily without hesitation, and then
settle back easily when the pressure is removed.

2. To check the valve for drip-tight closure, a line should be
connected from the inlet to the cover, and pressure applied at the
inlet of the valve. If properly assembled, the valve should hold
tight with as low as ten PSI at the inlet. See “Tight Sealing
Check” section.)

3. With the line connected from the inlet to the cover, apply full
working pressure to the inlet. Check all around the cover for any
leaks. Re-tighten cover nuts if necessary to stop leaks past the
diaphragm.

4. Remove pressure, then re-install the pilot system and tubing
exactly as it was prior to removal. Bleed air from all high

points.

5. Follow steps under “Start-Up and Adjustment” Section in

Technical Manual for returning complete valve back to service

INSTALLATION / OPERATION / MAINTENANCE

Description 100-01 Hytrol Valve

The CIa-VaI Model 100-01 Hytrol Valve is a main valve for

CIa-VaI Automatic Control Valves. It is a hydraulically operated,

diaphragm-actuated, globe or angle pattern valve.

This valve consists of three major components; body, diaphragm

assembly, and cover. The diaphragm assembly is the only

moving part. The diaphragm assembly uses a diaphragm of nylon

fabric bonded with synthetic rubber. A synthetic rubber disc,

contained on three and one half sides by a disc retainer and disc

guide, forms a seal with the valve seat when pressure is applied

above the diaphragm. The diaphragm assembly forms a sealed

chamber in the upper portion of the valve, separating operating

pressure from line pressure.

Description 100-20 600 Series Hytrol Valve

The CIa-VaI Model 100-20 Hytrol Valve (600 Series main valve)

have only one part -the body- that is different from standard 100

Series Cla-Val main valve parts. The remaining parts of the 600

series main valve are standard Cla-Val main valve parts. All serv-

ice and maintenance information for the standard 100 Series

main valves also apply to the 600 series main valves.

The most important thing to remember when ordering main

valve repair kits and replacement parts, except for the body, all

other parts are going to be for a smaller size main valve. Cla-

Val identifies main valve parts with the flange size of the stan-

dard 100 Series main valve. Refer to the "Main Valve Sizes”

100-01 Hytrol Main Valve Assembly

UNDERSTANDING THE 600 SERIES VALVES

In 1987, Cla-Val introduced the Model 100-20 Hytrol as the basic
main valve for the 600 Series of automatic control valves. To
identify all new valves using the 100-20 Hytrol, an existing cata­log number is modified. Making a 600 Series catalog number is
simply done by using a "6" in front of the two digit catalog num­bers or replacing the "2" with a "6" in three digit catalog num­bers. Current schematics reflect both catalog numbers together
separated by a slash ( i.e. - 90-01/690-01, 58-02/658-02, 210­01/610-01, etc). Since these two valves 'share' the same catalog
number and schematic, they provide the same function in a sys­tem. The only difference between the two valves is the relative
capacity of the two main valve series.

The 100-01 Hytrol is the basic main valve for Cla-Val automatic
control valves. This valve is the current version of the Clayton
Hytrol valve design originated in 1936. The 100-01 Hytrol is
designed as a full flow area valve. This means that the inlet,
seat and outlet openings are the same size. Thus, the pressure
drop is kept to a minimum for this globe style design.

The 100-20 Hytrol valve has all of the basic features and advan­tages of the original 100-01 Hytrol. Only one part has been
changed - the body. It is designed with different size inlet, seat
and outlet openings. The 100-20 Hytrol has inlet and outlet
flanges one valve size larger than the seat opening size. This
results in what is sometimes called a ''reduced port' main valve.
For example, a 4" 100-20 valve has a 3" seat. Note: valve size
is always determined by the flange size. The following chart
compares the 100-01 and the 100-20 main valves.

MODEL

INSTALLATION / OPERATION / MAINTENANCE

SERVICE AND MAINTENANCE OF 600 SERIES
VALVES

The 600 series main valves have only one part -the body- that is
different from standard 100 Series Cla-Val main valve parts. The
remaining parts of the 600 series main valve are standard Cla­Val main valve parts. All service and maintenance information
for the standard 100 Series main valves in this manual also
apply to the 600 series main valves.

The most important thing to remember when ordering main valve
repair kits and replacement parts, except for the body, all other
parts are going to be for a smaller size main valve. Cla-Val iden­tifies main valve parts with the flange size of the standard 100
Series main valve. Refer to the "Main Valve Sizes Comparison"
chart. For example, if you are servicing a 6" 100-20 Hytrol and
needed a repair kit, you would order a repair kit for a 4" 100-01
Hytrol. This kit is also suitable for a 6" 100-20 Hytrol. Complete
Technical Manuals include a repair kit data sheet N-RK that
shows this relationship.

When you order repair parts, it is a good idea to include valve
nameplate data (size, catalog number, and part number) and
description of the parts desired. Do this to be sure parts will fit
the valve you are working on and not be too big for it. Pilot con­trols and repair kits maintenance information remain the same
for 100 or 600 Series valves.

Cla-Val Main Valves

Catalog Number

The 100-20 Hytrol is available only in ductile iron, 150 and 300
pressure class, and Bronze trim standard. Available extra cost
main valve options include stainless steel trim, epoxy coating,
Dura-Kleen stem, Delrin sleeved stem, and high temperature rub­ber parts. All four basic main valves have a 600 Series version
available with all of the same benefits and size relationships.

Bulletin 8320 is a small 3-way solenoid operated valve with all three
pipe connections located in the body. The bodies are of brass or stain­less steel construction. Standard valves have General Purpose, Nema
Type 1 Solenoid Enclosures. Valves that are equipped with a solenoid
enclosure which is designed to meet Nema Type 4-Water tight, Nema
Type 7 (C or D) Hazardous Locations - Class I, Group C or D, and
Nema Type 9 (E, F or G) Hazardous Locations - Class II, Group E, F or
G are shown on separate sheets of Installation and Maintenance
Instructions, Form Numbers V-5391 and V-5381.

Check Nameplate for correct Catalog Number, pressure, voltage and
service.

Valves with suffix "MO" or "MS" in catalog number are provided with a
Manual Operator which allows manual operation when desired or dur­ing an interruption of electrical power.

INSTALLATION

Valve may be mounted in any position

POSITIONING

Connect piping to valve according to markings on valve body. Refer to
Flow Diagram provided. Apply pipe compound sparingly to male pipe
threads only; if applied to valve threads, it may enter valve and cause
operational difficulty. Pipe strain should be avoided by proper support
and alignment of piping. When tightening pipe, do not use valve as
lever.

PIPING

Wiring must comply with local and National Electrical Codes. For
valves equipped with an explosion-proof, watertight solenoid enclo­sure, the electrical fittings must be approved for use in the approved
hazardous locations. Housings for all solenoids are made with connec­tions for 1/2 inch conduit. The general purpose enclosure may be rotat­ed to facilitate wiring by removing the retaining cap.

WIRING

OPERATION

Normally Closed: Applies pressure when solenoid is energized:

exhausts pressure when solenoid is de-energized
Normally Open: Applies pressure when solenoid is de-energized;
exhausts pressure when solenoid is energized.
Universal: For normally closed or normally open operation, selection
or diversion of pressure can be applied at port 1 (A), 2 (B), or 3 (C).

COIL REPLACEMENT

(REF. FIG. 2)

Alternating Current (A-C) and Direct Current (D-C) solenoids are built
differently. To convert from one to other, it is necessary to change the
complete solenoid, including the core assembly.

Turn off electrical power, disconnect coil lead wires and proceed as
follows:

Spare Parts Kits and Coils are available for ASCO valves. Parts
marked with

Standard catalog valves are supplied with coils designed for contin­uous duty service. When the solenoid is energized for a long period,
the solenoid enclosure becomes hot and can be touched with the
bare hand for only an instant. This safe operating temperature. Any
excessive heating will be indicated by the smoke and odor of burn­ing coil insulation.

CLEANING

A periodic cleaning of all valves is desirable. The time between
cleanings will vary, depending on the media and service conditions.
In general, if the voltage to the coils is correct, sluggish valve oper­ation or excessive leakage will indicate that cleaning is required.

IMPROPER OPERATION

Faulty Control Circuit: Check the electrical system by energiz-

ing the solenoid. A metallic click signifies the solenoid is operat­ing. Absence of the click indicate loss of power supply. Check for
loose or blown-out fuses, open-circuited or grounded coil, broken
lead wires or splice.
Burned-out Coil: Check for open-circuited coil. Replace coil, if
necessary.
Low Voltage: Check voltage across coil leads. Voltage must be
at least 85% of nameplate ratings.
Incorrect Pressure: Check valve pressure. Pressure to valve
must be within the range specified on nameplate.
Excessive Leakage: Disassemble valve and clean all parts.
Replace parts that are worn or damaged with a complete Spare
Parts Kit for best results.

Turn off electrical power supply and de-pressurize valve.

-SERVICE NOTICE-

ASCO®solenoid valves with design change letter "G" in the catalog
number (example: 8210G 1) have an epoxy encapsulated ASCO®Red
Hat II. solenoid. This solenoid replaces some of the solenoids with metal
enclosures and open-frame constructions. Follow these installation and
maintenance instructions if your valve or operator uses this solenoid.

DESCRIPTION

Catalog numbers 8016G1 and 8016G2 are epoxy encapsulated pull-type
solenoids. The green solenoid with lead wires and 1/2 " conduit connec­tion is designed to meet Enclosure Type 1 -General Purpose,Type 2­Dripproof,Types 3 and 3S-Raintight, and Types 4 and 4X-Watertight. The
black solenoid on catalog numbers prefixed "EF" is designed to meet
Enclosure Types 3 and 3S-Raintight, Types 4 and 4X-Watertight, Types 6
and 6P-Submersible, type 7 (A, B, C, & D) Explosionproof Class 1,
Division 1, Groups A, B, C, & D and Type 9 (E, F, & G)-Dust-lgnitionproof
Class 11, Division 1, Groups E, F, & G. The Class 11, Groups F & G Dust
Locations designation is not applicable for solenoids or solenoid valves
used for steam service or when a class "H" solenoid is used. See
Temperature Limitations section for solenoid identification and name­plate/retainer for service. When installed just as a solenoid and not
attached to an ASCO valve, the core has a 0.250-28 UNF-2B tapped hole,

0.38 minimum full thread.

Series 8016G solenoids are available in:

• Open-Frame Construction

The green solenoid may be supplied with 1/4 spade, screw, or
DIN terminals (Refer to Figure 4).

• Panel Mounted Construction

These solenoids are specifically designed to be panel mounted by the
customer through a panel having a .062 to .093 maximum wall thickness.
(Refer to Figure 3 and section on Installation of Panel Mounted

Solenoid).

Optional Features For Type 1—General Purpose
Construction Only

• Junction Box

This junction box construction meets Enclosure Types 2,3,3S,4, and
4X. Only solenoids with 1/4" spade or screw terminals may have a
junction box. The junction box provides a 1/2 conduit connection,
grounding and spade or screw terminal Connections within the junction
box (See Figure 5).

• DIN Plug Connector Kit No. K236 - 034

Use this kit only for solenoids with DIN terminals. The DIN plug connector kit
provides a two pole with grounding contact DIN Type 43650 construction
(See Figure 6).

OPERATION

When the solenoid is energized, the core is drawn into the solenoid base sub­assembly. IMPORTANT: When the solenoid is de-energized, the initial
return force for the core, Whether developed by spring, pressure, or
weight, must exert a minimum force to overcome residual magnetism cre­ated by the solenoid. Minimum return force for AC construction is 11 ounces,
and 4 ounces for DC construction.

INSTALLATION

Check nameplate for correct catalog number, service, and wattage. Check front
of solenoid for voltage and frequency.

WARNING: To prevent the possibility of electrical shock from
the accessibility of live parts, install the open-frame solenoid

in an enclosure.

FOR BLACK ENCLOSURE TYPES 7 AND 9 ONLY

CAUTION: To prevent fire or explosion, do not install solenoid and/or valve

where ignition temperature is less than 165˚ C. On valves used for steam
service or when a class "H" solenoid is used, do not install in hazardous atmos­phere where ignition temperature is less than 180˚ C. See nameplate/retainer for service.
NOTE: These solenoids have an internal non-resetable thermal fuse to limit
solenoid temperature in the event that extraordinary conditions occur which could
cause excessive temperatures. These conditions include high input voltage,
a jammed core, excessive ambient temperature or shorted solenoid, etc.
This unique feature is a standard feature is a standard feature only in
solenoids with black explosionproof/dust-ignitionproof enclosures
(types 7&9).

IMPORTANT: To protect the solenoid valve or operator, install a strain­er or fi lter, suitable for the service involved in the inlet side as close to the
valve or operator as possible. Clean periodically depending on service con­dition & See ASCO Series 8600, 8601, and 8602 for strainers.

Temperature Limitations

For maximum valve ambient temperatures, refer to chart. The temperature limi­tations listed, only indicate maximum application temperatures for field wiring
rated at 90°C. Check catalog number prefix and watt rating on nameplate to
determine maximum ambient temperature. See valve installation and mainte­nance instructions for maximum fluid temperature. NOTE: For steam service,
refer to Wiring section, Junction Box for temperature rating of supply wires.

Minimum ambient temperature -40° F (-40° C). Positioning

Positioning

This solenoid is designed to perform properly when mounted in any position.
However, for optimum life and performance, the solenoid should be mounted ver­tically and upright to reduce the possibility of foreign matter accumulating in the
solenoid base sub-assembly area.

Wiring

Wiring must comply with local codes and the National Electrical Code. All sole­noids supplied with lead wires are provided with a grounding wire which is green
or green with yellow stripes and a 1/2" conduit connection. To facilitate wiring, the
solenoid may be rotated 360˚. For the watertight and explosionproof solenoid,
electrical fittings must be approved for use in the approved hazardous locations.

Addi t i onal Wiring Instructi o n s Fo r Opti onal Feat ures :

• Open-Frame solenoid with 1/4" spade terminals

The junction box is used with spade or screw terminal solenoids only
and is provided with a grounding screw and a 1/2" conduit connection.
Connect #12-18AWG standard copper wire only to the screw terminals.
Within the junction box use field wire that is rated 90°C or greater for
connections. For steam service use 105°C rated wire up to 50 psi or
use 125°C rated wire above 50 psi. After electrical hookup, replace
cover gasket, cover, and screws. Tighten screws evenly in a crisscross man-

ner.

• DIN Plug Connector Kit No. KC236-034

1. The open—frame solenoid is provided with DIN terminals to accommodate
the DIN plug connector kit.

2. Remove center screw from plug connector. Using a small screwdriver,
pry terminal block from connector cover.

3. Use #12-18 AWG stranded copper wire rated at 90°C or greater for
connections. Strip wire leads back approximately 1/4" for installation in
socket terminals. The use of wire-end sleeves is also recommended

for

these socket terminals. Maximum length of wire-end sleeves to be
approximately 1/4". Tinning of the ends of the lead wires is not recommended.

4. Thread wire through gland nut, gland gasket, washer, and connector

cover.

NOTE: Connector cover may be rotated in 90° increments from position
shown for alternate positioning of cable entry.

5. Check DIN connector terminal block for electrical markings. Then make
electrical hookup to terminal block according to markings on it. Snap
terminal block into connector cover and install center screw.

6. Position connector gasket on solenoid and install plug connector.
Torque center screw to 5 ± 1 in-lbs (0,6 ± 1,1 Nm).

NOTE: Alternating current (AC) and direct current (DC) solenoids are built
differently. To convert from one to the other, it may be necessary to
change the complete solenoid including the core and solenoid base sub­assembly, not just the solenoid. Consult ASCO.

Installation of Solenoid

Solenoids may be assembled as a complete unit. Tightening is accomplished
by means of a hex flange at the base of the solenoid. The 3/4" bonnet
construction (Figure 1) must be disassembled for installation and installed
with a special wrench adapter.

Installation of Panel Mounted Solenoid (See Figure 3)

Disassemble solenoid following instruction under Solenoid Replacement
then proceed

3/4" Valve Bonnet Construction

1. Install retainer(convex side to solenoid) in 1.312 diameter mounting hole
in customer panel.

2. Then position spring washer over plugnut/core tube sub-assembly.

3. Install plugnut/core tube sub-assembly through retainer in customer
panel. Then replace solenoid, nameplate/retainer and red cap.

15/16" Valve Bonnet Construction

1. Install solenoid base sub-assembly through 0.69 diameter mounting
hole in customer panel.

2. Position spring washer on opposite side of panel over solenoid base
sub-assembly then replace.

Solenoid Temperature

Standard solenoids are designed for continuous duty service. When the
solenoid is energized for a long period, the solenoid becomes hot and can
be touched by hand only for an instant. This is a safe operating temperature.

MAINTENANCE

WARNING: To prevent the possibility of personal injury or property dam­age, turn off electrical power, depressurize solenoid operator and/or
valve, and vent fluid to a safe area before servicing.

Cleaning

All solenoid operators and valves should be cleaned periodically. The
time
between cleaning will vary depending on medium and service conditions.
In general, if the voltage to the solenoid is correct, sluggish valve operation,
excessive noise or leakage will indicate that cleaning is required. Clean
strainer or filter when cleaning the valve,

Preventive Maintenance

• Keep the medium flowing through the solenoid operator or valve as
free from dirt and foreign material as possible.

• While in service, the solenoid operator or valve should be operated at
least once a month to insure proper opening and closing.

• Depending on the medium and service conditions, periodic inspection
of internal valve parts for damage or excessive wear is recommended.
Thoroughly clean all parts. Replace any worn or damaged parts.

Causes of Improper Operation

• Faulty Control Circuit: Check the electrical system by energizing the

solenoid. A metallic click signifies that the solenoid is operating.
Absence of the click indicates loss of power supply. Check for loose or
blown fuses, open-circuited or grounded solenoid, broken lead wires or

splice connections.

• Burned-Out Solenoid: Check for open-circuited solenoid. Replace

if necessary. Check supply voltage; it must be the same as specified on

nameplate/retainer and marked on the solenoid. Check ambient temperature
and check that the core is not jammed.

• Low Voltage: Check voltage across the solenoid leads. Voltage must
be at least 85% of rated voltage.

Solenoid Replacement

1. On solenoids with lead wires disconnect conduit, coil leads, and
grounding wire.

NOTE: Any optional parts attached to the old solenoid must be reinstalled
on the new solenoid.

2. Disassemble solenoids with optional features as follows:

• Spade or Screw Terminals

Remove terminal connections, grounding screw, grounding wire, and
terminal block (screw terminal type only).

NOTE: For screw terminals, the socket head screw holding the terminal
block serves as a grounding screw.

• Junction Box
Remove conduit and socket head screw (use 5132" hex key wrench)
from center of juncti on box . Disconnect junction box from sole-

noid.

• DIN Plug Connector
Remove center screw from DIN plug connector. Disconnect DIN plug
connector from adapter. Remove socket head screw (use 5/32" hex

key wrench), DIN terminal adapter, and gasket from solenoid.

3. Snap off red cap from top of solenoid base sub-assembly.

4. Push down on solenoid. Then using a suitable screwdriver, insert blade
in slot provided between solenoid and nameplate/retainer. Pry up
slightly and push to remove. Then remove solenoid from solenoid base
sub-assembly.

5. Reassemble using exploded views for parts identification and placement

Disassembly and Reassembly of Solenoids

1. Remove solenoid, see Solenoid Replacement.

2. Remove finger washer or spring washer from solenoid base sub-assembly.

3. Unscrew solenoid base sub-assembly.

NOTE: Some solenoid constructions have a plugnut/core tube
sub-assembly, bonnet gasket and bonnet in place of the solenoid base
sub-assembly. To remove bonnet use special wrench adapter supplied in
ASCO Rebuild Kit. For wrench adapter only, order ASCO Wrench Kit
No.K218 - 948.

4. The core is now accessible for cleaning or replacement.

5. If the solenoid is part of a valve, refer to basic valve installation and
maintenance instructions for further disassembly.

6. Reassemble using exploded views for identification and placement of
parts.

The strainer is designed for use in conjunction with a Cla-Val
Main Valve, but can be installed in any piping system where
there is a moving fluid stream to keep it clean. When it is used
with the Cla-Val Valve, it is threaded into the upstream body port
provided for it on the side of the valve. It projects through the
side of the Main Valve into the flow stream. All liquid shunted to
the pilot control system and to the cover chamber of the Main
Valve passes through the X46 Flow Clean Strainer.

• Self Scrubbing Cleaning Action

• Straight Type or Angle Type

The Cla-Val Model X46 Strainer is designed to prevent passage of
foreign particles larger than .015". It is especially effective against
such contaminant as algae, mud, scale, wood pulp, moss, and root
fibers. There is a model for every Cla-Val. valve.

The X46 Flow Clean strainer operates on a velocity principle utiliz­ing the circular "air foil" section to make it self cleaning. Impingement
of particles is on the "leading edge" only. The low pressure area on
the downstream side of the screen prevents foreign particles from
clogging the screen. There is also a scouring action, due to eddy
currents, which keeps most of the screen area clean.

INSPECTION

Inspect internal and external threads for damage or evidence
of cross-threading. Check inner and outer screens for clogging,
embedded foreign particles, breaks, cracks, corrosion, fatigue,
and other signs of damage.

CLEANING

After inspection, cleaning of the X46 can begin. Water service usually will produce
mineral or lime deposits on metal parts in contact with water. These deposits can
be cleaned by dipping X46 in a 5-percent muriatic acid solution just long enough
for deposit to dissolve. This will remove most of the common types of deposits.
Caution: use extreme care when handling acid. If the deposit is not removed
by acid, then a fine grit (400) wet or dry sandpaper can be used with water.
Rinse parts in water before handling. An appropriate solvent can clean parts used
in fueling service. Dry with compressed air or a clean, lint-free cloth.
Protect from damage and dust until reassembled.

REPLACEMENT

If there is any sign of damage, or if there is the slightest doubt that the Model X46
Flow Clean Strainer may not afford completely satisfactory operation, replace it.
Use Inspection steps as a guide. Neither inner screen, outer screen, nor housing is
furnished as a replacement part. Replace Model X46 Flow Clean Strainer as a com­plete unit.

When ordering replacement Flow-Clean Strainers, it is important to determine pipe
size of the tapped hole into which the strainer will be inserted (refer to column A or
F), and the size of the external connection (refer to column B or G).

When Ordering,
Please Specify:

• Catalog Number X46

• Straight Type or Angle Type

• Size Inserted Into and Size Connection

• Materials

DISASSEMBLY

Do not attempt to remove the screens from the strainer housing.
