Principle of Operation

Powertrol Valve

100-02

DESCRIPTION

This manual contains information for installation, operation and main­tenance of the Cla-Val Co. 100-02 Powertrol, an automatic valve
designed for use where independent operating pressure is desired,or
when line fluid is unsuitable as an operating medium.

This valve is a hydraulically operated, diaphragm type, globe or angle
pattern valve. it is single seated and incorporates into its design two
operating chambers sealed from one another by a flexible synthetic
rubber diaphragm. Pressure applied to the upper chamber closes the
valve; when applied to the lower chamber, it opens the valve.

With proper pilot controls, the valve can be held in any intermediate
position between fully open and tightly closed.

INSTALLATION

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

NOTE: BEFORE THE VALVE IS INSTALLED, PIPE LINES
SHOULD BE FLUSHED OF ALL CHIPS, SCALE AND FOREIGN
MATTER.

It is recommended that gate or block valves be installed on both the
upstream and downstream sides of the 100-02 to facilitate isolating
the valve for preventative maintenance.
Place the valve in the line with flow through the valve in the direction
indicated on the inlet name plate or by flow arrows.
Cla-Val Powertrol Valves operate with maximum efficiency when
mounted in horizontal piping with cover "UP,' however, other positions
are acceptable. Due to the size and weight of the cover and internal
assembly of 4" and larger valves, installation with the cover "UP" is
advisable. This makes periodic inspection of internal parts readily
accessible.
When a pilot control system is installed on the Powertrol Valve, use
care to prevent damage. If it is necessary to remove fittings or com­ponents, be sure they are kept clean and replaced in the exact order
of removal.
After the valve is installed and the system is first pressurized, vent air
from the cover chamber and tubing by loosening fit" sings at all high
points.

Full Open Operation

When operating pressure below the
diaphragm is applied and operating, pressure
is relieved from the cover chamber, the valve
is held open, allowing full flow.

Modulating Action

The valve holds any intermediate position
when operating pressure is equal above and
below the diaphragm. A Cla-Val four-way pilot
control with "lock" position can maintain this
balance by stopping flow in the pilot control
system.

Tight Closing Operation

When pressure below the diaphragm is
relieved and operating pressure is applied to
the cover chamber, the valve closes drip-tight.

TROUBLE SHOOTING

The following trouble shooting information deals strictly with the
Powertrol Valve; however some 'impossible causes" will refer to compo­nents that may exist in the variety of control systems available for the
valve. All trouble shooting is possible without removing the valve from
the line.

CAUTION: Extreme care should be taken when servicing the valve.
Gate or line block valves must be closed upstream and downstream of
the valve before starting disassembly. When there are no block or gate
valves to isolate the Powertrol Valve it should be realized that the valve
cannot be serviced under pressure. Steps must be taken to remedy this
situation before proceeding.

FREEDOM OF MOVEMENT

The following procedures can be used to determine if the
valve opens and closes fully. During this test the diaphragm
can be checked for damage.

1.The Powertrol Valve will have a control to open and close
the valve. Position the control so that pressure is applied to
the cover chamber (above the valve diaphragm). This will
close the Powertrol Valve. Check the drain from the control
that discharges to atmosphere.

Once the liquid from the lower diaphragm chamber is drained
the discharge should stop. If the discharge continues after the
normal time it takes to drain then the diaphragm is damaged,
or the stem nut is loose, or the stem o-ring is leaking. If the
discharge is continuous from both chambers then there is a
possibility that the diaphragm or the pilot control is damaged.

If the valve is equipped with a "Dry Drain" (control drain piped
to downstream end of the valve) then same procedure is fol­lowed except the CK2 Shutoff Cock on the downstream end
of the valve must be closed and the drain line disconnected
and drained to atmosphere. It can then be checked as above.

Measurement of the vertical travel of the stem (diaphragm
assembly) will make it possible to determine if the travel, or
stroke is restricted. The following chart provides this mea­surement. It is necessary to have either the X101 Valve
Position Indicator or X105 Limit Switch Assembly installed on
the valve to visually check the travel.

Mark the position of the stem on the X101 or X105 when the
valve is closed. Reposition the control so that pressure is
applied below the diaphragm and the cover chamber is
drained. Determine the extent of the stem travel. Check this
movement with the stem travel chart. If the stroke is different
than listed (5% to 10%) then there is good reason to believe
something is mechanically restricting the stroke of the valve
at one end of its travel. If it is determined that flow does not
stop through the valve when in the indicated "closed" position,
the obstruction probably is between the disc and the seat, or
in the power unit chamber below the diaphragm. If the flow
stops, the obstruction is likely in the cover chamber above the
diaphragm or possibly above the disc retainer. Refer to the
sectional view under Principle of Operation.

If operation of the valve a few times does not dislodge the for­eign object obstructing the diaphragm assembly (stem) move­ment then the valve must be disassembled and the problem
located and corrected. See disassembly instructions.

SYMPTOM

Valve fails to
close.

Valve fails to
open.

Valve closes but
leakage occurs.

O-Ring failure

*POSSIBLE
CAUSE

Stem stuck in open position.

Worn diaphragm
or loose upper
stem nut

Foreign object on
valve seat.

Pressure not being
released from power
unit chamber.

Operating
pressure not
getting into valve
cover.

Insufficient
line pressure.

Stem stuck in
closed or semi­open position.

Worn diaphragm
or loose upper
stem nut.

Foreign object on
top of disc retainer

Pressure not being
released from
cover chamber.

Operating pressure not
applied into power
unit chamber.

Worn disc or seat.

Mineral deposits
on stem cause
abrasion on ring.

TEST
PROCEDURE

Vent power unit cham­ber. Apply pressure to
cover chamber. Valve
should close.

Apply pressure in
power unit chamber
and vent cover.
Continuous flow from
cover indicates this
trouble.

Valve opens okay but
only closes part way.

Make sure
pressure is being
released by opening a
fitting into the cham­ber. If valve then clos­es refer to remedy.

Use pressure gauge
or loosen cover plug
to check for pressure.

Check line pressure.

Vent cover. Apply
pressure to power unit
chamber.

Apply pressure in
power unit chamber
and vent cover.
Continuous flow from
cover indicates this
pro bleary.

Valve closed okay
but won't open all
the way.

Open a fitting or
remove a plug from
cover chamber if
cover chamber vents
and valve opens, see
remedy.

Loosen a fitting in this
chamber to check for
pressure at this point.

The best procedure
here is to disassemble
the valve and inspect
these parts.

Remove pressure
from both cover and
power unit chambers
and apply line pres­sure to valve. Open
line from power unit
chamber and observe
continuos flow.

REMEDY

Disassemble, examine
all internal parts for
cause of the sticking
condition and clean off
scale deposits.

Disassemble and
replace diaphragm or
tighten the valve stem
nut.

Try operating valve a
few times. This might
dislodge the object. If
this fails, disassemble
and remove the
obstruction.

Check control
system. Tube line or
nipple might be plugged
up.

Clean tubing or pipe fit­tings into cover cham­ber. Open CK2 Isolation
Valve in control lines.

Establish line pressure.

Disassemble, examine
all internal parts for
cause of the sticking
pro bleary, and clean off
scale deposits.

Disassemble and
replace diaphragm or
tighten valve stem nut.

Try operating valve a
few times. This might
dislodge the object. if
this fails disassemble
and remove the
obstruction.

Check control system.
Check lines or pipe fit­tings. Clean out any
plugged lines.

Clean tubing or pipe fit­tings into power unit
chamber.

Replace worn parts.

Disassemble and
replace O-ring.

*Assuming control system is functioning properly.

STEM TRAVEL

(Fully open to fully closed)

VALVE SIZE VALVE SIZE

When block and tackle or a power hoist is to be used to lift the valve cover
insert a proper size eye bolt in place of the center cover plug. Pull cover
straight up to keep from damaging the power unit stem bearing and upper
stem.

On valves 1" and larger remove the power unit retaining nuts. The power
unit body can now be lifted from the valve body. The stem with diaphragm
assembly and disc retainer assembly will be removed with the power unit
body.

CAUTION: During service performed on the stem assembly, the stem sur­faces must not be damaged. If a vice or other holding device is used to grip
the stem, soft jaws of brass or copper must be used to protect the precision
ground surface of the stainless steel stem. If the stem is marred no amount
of careful dressing can restore the stem to its original condition.

REASSEMBLY

To reassemble, reverse the order of disassembly.

1. If the disc has been removed, it is important that correct pressure be
on the disc from the disc guide when the lower stem nut is tight. Use suf­ficient spacer washers to obtain slight pressure (by visual indentation) on
the disc. This applies to 1" through 16" valves. Refer to seat and disc
detail drawings for location of spacer washers for various valve sizes.

Note: New discs will usually require a different number of spacer wash­ers to obtain the right amount of 'grip (slight indentation) on the disc.

6. Inspect the threads on the stem. Mineral deposits that prevent the
nuts from turning must be cleaned from the threads A 5C.h solution of
muriatic acid will soften mineral or scale deposits to assist in removal of
nuts and general cleaning of parts. Flush the parts thoroughly with water
immediately after cleaning.

Care must always be exercised when handling acid. Read the warning
label on the acid container to be sure of correct method of use and dis­posal after use.

7. Remove the upper stem nut, upper diaphragm washer, diaphragm
and lower diaphragm washer. The stem with the disc retainer assembly
can now be removed from the power unit body

8. Hold the stem in a vice with soft jaws and remove the lower stem nut.
Remove the lock washer, disc retainer, space washer(s) and disc Refer
to the sectional view of the valve size being serviced. This will assist in
the disassembly procedure outlined above. The reassembly instructions
outlining proper procedure and quantity of space washers. This is espe­cially important if the disc is replaced.

Inspection of Parts

1. Returning to the valve body in the line, the seat should now be
inspected for damage. if the seat requires removal use the following
tools. Seats in valve sizes 1/2" and 3/4" can be removed with a hex sock­et wrench. Seats in valve sizes 1" through 6" should be removed with
accessory X-109 Seat Removing Tool available from the factory. Seats
in valve sizes 3" through 16" may be removed with a screw driver. If upon
removal of the screws the seat cannot be lifted out, it will be necessary
to use a hard rubber mallet and tap the seat loose.

2. Any buildup of mineral or scale should be cleaned from the valve body
at this time. Inspection of the cover and power unit body surfaces that
contact the diaphragm is important. Clean and smooth, with wet or dry
emery paper, any roughness that could damage the diaphragm. Inspect
and recondition the surface on the upper and lower diaphragm washers.
The perimeter of the diaphragm washers is the most likely area to cause
diaphragm wear if the surface is not smooth. Take extra care to make
this a smooth finish.

3. Inspect the power unit body bearing insert o-ring that is in contact with
the stem. If it is worn, nicked or cut, replace it.

4. Inspect the diaphragm for cracks or chafing. Replace the diaphragm
if damaged.

Inspect the disc and replace if the surface is damaged or worn. If a new
disc is not available, the existing disc can be turned over, exposing the
unused surface for contact with the seat.

6. The disc guide should be checked and cleaned of scales and mineral
deposits. Due to the close tolerance between the outer periphery of the
disc guide and the inner area of the valve seat, no scale or mineral
deposits should be overlooked.

MAINTENANCE

Preventative Maintenance

The Cla-Val Co Powertrol Valves require no lubrication or packing
and a minimum of maintenance. However, a periodic inspection
schedule should be established to determine how the fluid velocity
as well as the substances occurring in natural waters are affecting
the valve These substances can be dissolved minerals. colloidal
and suspended particles. Effect of these actions or substances must
be determined by inspection.

DISASSEMBLY

1. First mark the side of the valve cover, power unit body and valve body so
that reassembly of these parts will be exactly as removed.

2. The Powertrol Valve inspection or maintenance can be accomplished
without removal of the valve body from the line. Shut off pressure to the
valve, both inlet, outlet and independent operating pressure when used.

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

3. After pressure has been released from the valve control system and oper­ating chambers of the valve, remove the controls and tubing. Obtain a
schematic of the assembly or note and sketch position of tubing and controls
for reassembly. Replacing tubing into the control ports exactly as removed is
necessary. Failure to reassemble properly will cause the valve to malfunc­tion and possibly cause serious damage.

4. Remove cover nuts and 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. See Figure 1.

1. If the disc has been removed, it is important that correct
pressure be on the disc from the disc guide when the lower
stem nut is tight. Use sufficient spacer washers to obtain
slight pressure (by visual indention) on the disc. Indention
should be slight and no looseness evident. This adjust­ment applies to 1 " through 16". Refer to seat and disc
detail drawings for location of spacer washers for various
valve sizes.

NOTE: New discs will usually require a different number of
spacer washers to obtain the right amount of "grip'' on the
disc.

2. The stem, with the disc assembly, can now be inserted
through the power unit body. Note sectional view for cor­rect position of the power unit body and stem assembly

3. Install on the cover end of the stem the lower diaphragm
washer,the diaphragm, the upper diaphragm washer, then
screw on the upper stem nut.

4. Tighten the upper stem nut securely so the diaphragm
and upper and lower diaphragm washer cannot be turned
on the stem. During the tightening of the upper stem nut
the lower stem nut can be held in a vice, or with a second
wrench.

5. Replace the gasket on the body. If an o-ring seal is used
as a gasket, valve size 4" through 16", a light coating of
grease can be applied to the power unit body groove to
hold the o-ring in place while installing on the body. The
power unit body must be replaced so that the index marks
applied in Disassembly Step 1 align. The control tubing will
then be able to be reassembled without difficulty.

6. Replace cover chamber spring on the upper diaphragm
washer. NOTE: Some valves may not have a cover cham­ber spring.

7. Place the cover on the power unit body aligning the
index marks. Secure the cover with 8 stud nuts. Tighten
the nuts firmly with a cross-over pattern until all nuts are
tight:

8. Reinstall the control system and tubing exactly as it was
before disassembly.

9.The Powertrol Valve can be tested for tight closure as well as
the tightness of the seal across the diaphragm.

a.The downstream or outlet shutoff valve remains closed

b. If the control system has a pilot or control that can position the
valve to a closed position, put the control in a position to close
the Powertrol. Lacking a control, inlet pressure must be tubed to
the Powertrol cover.

c. Open upstream gate or line block valve just enough to allow
flow.

d. Have the power unit body, center section, open to atmosphere
The power unit body will be atmospheric if the control is being
used.

e. Partially disconnect a fitting on the discharge side of the valve.
Do not remove fully unless there is no pressure.

f. After the valve is in the closed position for a few minutes, all
draining of the power unit body should stop. This will indicate a
good seal across the valve seat and the diaphragm.

600 Series

Powertrol Valve

The Cla-Val Model 100-21 is a hydraulically operated,
diaphragm actuated, globe or angle pattern valve. It consists
of four major components: the body, intermediate chamber,
diaphragm assembly and cover. The diaphragm assembly is
the only moving part.

The diaphragm assembly, which is guided top and center by
a precision machined stem, utilizes a non-wicking diaphragm
of nylon fabric bonded with synthetic rubber. The diaphragm
forms a seal between the cover chamber and intermediate
chamber. A synthetic rubber disc retained on three and one­half sides forms a drip-tight seal with the renewable seat
when pressure is applied above the diaphragm. As pressure
above the diaphragm is relieved and pressure is applied
below the diaphragm, the valve opens wide for full flow. The
rate of closing or opening can be controlled by modulating
the pressure above or below the diaphragm.

The Model 100-21 is recommended where independent
operating pressure is desired. The valve's packless
construction and simplicity of design assures a long life and
dependable operation. Available in various materials and in
a wide range of sizes. It's applications are many and varied.

100-21

Principle of Operation

The valve holds any intermediate
position when operating pressure is
equal above and below the
diaphragm. A Cla-Val four-way pilot
control with "lock" position can
maintain this balance by
stopping flow in the pilot
control system.

Service and Installation

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other
positions are acceptable. Due to component size and weight of 10 inch and larger valves, installation with cover UP is advisable. We recommend
isolation valves be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should be
considered essential. A regular maintenance program should be established based on the specific application data. However, we recommend a
thorough inspection be done at least once a year. Consult factory for specific recommendations.

INSTALLATION / OPERATION / MAINTENANCE

Flow Control

CV

MODEL

N-CV (R-1/09)

DESCRIPTION

The Cla-Val Model CV Flow Control is a simply-designed,
spring-loaded check valve. Rate of flow is full flow in one direc­tion and restricted in other direction. Flow is adjustable in the
restricted direction. It is intended for use in conjunction with a
pilot control system on a Cla-Val Automatic Control Valve.

OPERATION

The CV Flow Control permits full flow from port A to B, and
restricted flow in the reverse direction. Flow from port A to B
lifts the disc from seat, permitting full flow. Flow in the reverse
direction seats the disc, causing fluid to pass through the clear­ance between the stem and the disc. This clearance can be
increased, thereby increasing the restricted flow, by screwing
the stem out, or counter-clockwise. Turning the stem in, or
clockwise reduces the clearance between the stem and the
disc, thereby reducing the restricted flow.’

INSTALLATION

Install the CV Flow Control as shown in the valve schematic
All connections must be tight to prevent leakage.

DISASSEMBLY

Follow the sequence of the item numbers assigned to the
parts in the cross sectional illustration for recommended
order of disassembly.

Use a scriber, or similar sharp-pointed tool to remove O-ring
from the stem.

INSPECTION

Inspect all threads for damage or evidence of cross­threading. Check mating surface of seat and valve disc for
excessive scoring or embedded foreign particles. Check
spring for visible distortion, cracks and breaks. Inspect all
parts for damage, corrosion and cleanliness.

CLEANING

After disassembly and inspection, cleaning of the parts 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 the parts in a 5-percent
muriatic acid solution just long enough for deposits 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.

REPAIR AND REPLACEMENT

Minor nicks and scratches may be polished out using a fine
grade of emery or crocus cloth; replace parts if scratches
cannot be removed.

Replace O-ring packing and gasket each time CV Flow
Control is overhauled.

Replace all parts which are defective. Replace any parts
which create the slightest doubt that they will not afford com­pletely satisfactory operation. Use Inspection steps as a
guide.

REASSEMBLY

Reassembly is the reverse of disassembly; no special tools
are required.

TEST PROCEDURE

No testing of the flow Control is required prior to reassembly
to the pilot control system on Cla-Val Main Valve.

Typical Application

Actuating Collar Adjustment

Minimum Setting

When adjusting actuating collar for proper switch
action, a clearance of at least 1/16" (1/8” for 24”
valve) must be provided between the collar and
the bushing gland nut when valve is in the fully
closed position.

Used for any electrical operation which can be
performed by either opening or closing a switch;
such as alarm systems, process control, pump
control, motor starting or stopping, etc. Readily
attached to most Cla-Val Valves.

1. Remove plug in top of
valve cover.

2. Screw actuating stem
into main valve stem.

3. Slip adapter down
over stem and screw
into place on valve
cover.

4. Attach micro switch
housing and bracket to
adapter with jam nut.

5. Bring electrical supply
circuit into unit through
the 1/2" tapping in
micro switch housing.

6. Adjust switch collars.
(Set collar to trip
switch after valve is

• Easy To Adjust

The Cla-Val Model X105L/X105L2 Limit Switch Assembly is a
rugged, dependable and positive acting switch assembly actuated
by the opening or closing of a Cla-Val control valve on which it is
mounted. The single pole, double throw micro switch can be
connected either to open or to close an electrical circuit when
actuated. By loosening the allen screw on the actuating collar and
raising or lowering the collar on the stem, the X105L is easily
adjusted to signal that the valve has fully reached the desired
position (open or closed).

Cla-Val Product

Identification

Proper Identification

For ordering repair kits, replacement parts, or for
inquiries concerning valve operation, it is important to
properly identify Cla-Val products already in service
by including all nameplate data with your inquiry.
Pertinent product data includes valve function, size,
material, pressure rating, end details, type of pilot
controls used and control adjustment ranges.

Identification Plates

For product identification, cast-in body markings are
supplemented by identification plates as illustrated on
this page. The plates, depending on type and size of
product, are mounted in the most practical position. It

is extremely important that these identification
plates are not painted over, removed, or in any
other way rendered illegible.
