Scope of the Manual

This manual covers instructions for the Types C471, C477 and C486 internal valves.

Description

The valves are typically used on the inlets and outlets of bobtail and transport trucks and on large stationary storage tanks. They can also be installed in-line. Designed for propane, butane or NH3 at ambient temperatures, the valves can be used on other compressed gases, but the user should check with the factory to make sure the valves are suitable for the particular service.

Specications

The Specications section on the following page shows specications for Types C471, C477 and C486 internal valves.

DOT Internal Self-Closing Stop Valve Requirement—

U.S. Department of Transportation (DOT) regulations 49CFR§178.337-8(a)(4) require each liquid or vapor discharge outlet on cargo tanks (except for cargo tanks used to transport chlorine, carbon dioxide, refrigerated liquid and

certain cargo tanks certied prior to January 1, 1995) to be tted with an internal self-closing stop valve. Fisher “C” Series

internal valves comply with the internal self-closing stop valve requirement under the DOT regulations.

1. The pressure/temperature limits in this Instruction Manual and any applicable standard or code limitation should not be exceeded.

2. Product has passed Fisher® testing for leakage down to -40ºF / -40ºC.

Principle of Operation

Refer to the schematic drawing, Figure 2. In view #1, the valve is held closed by both tank pressure and the valve’s closing spring. There is no leakage past the resilient seats in the poppet to the valve outlet.

The valve is opened by moving the operating lever to

approximately mid-point in its 70° travel (view #2). This

allows the cam to place the rapid equalization portion of the valve stem in the pilot opening, permitting a larger amount of product to bleed downstream than if the operating lever were moved to the full open position.

When tank and downstream pressure are nearly equal

after a few seconds, the excess ow spring pushes open

the main poppet (view #3) and the operating lever can be moved to the full open position.

If tank pressure is greater than the valve’s outlet pressure, the main poppet will remain in the closed position. If valve outlet piping is closed off by other valves, however, product bleeding through the pilot will increase until it nearly equals tank pressure and the main poppet opens.

Kalrez® is a mark owned by E.I. du Pont de Nemours and Co.

The main poppet will not open if valve outlet piping is not closed off so that the outlet pressure can approach tank pressure.

Once the main poppet opens, a flow greater than the valve’s excess flow spring rating or a sufficient surge in flow forces the main poppet closed against the excess flow spring (view #4). The pilot valve allows a small amount of product to bleed, but much less than view #2 where the rapid equalization portion of the stem is placed in the pilot opening. When the operating lever is moved to the closed position, the valve closes completely and seals tightly (view #1).

Installation

Mounting and Piping

The internal valves can be installed in either a half or full

coupling. Excess ow spring closing ow rates vary in half and full couplings, refer to the Specication section.

CAUTION

Excess ow valve closing ow rates are not

the same for half and full couplings. Verify

the coupling for the desired excess ow rate.

Do not install the valve in any piping tending to restrict the valve inlet because this may

prevent the excess ow valve from closing.

Do not install the valve with such extreme torque that the coupling can cut threads into the valve. This could cause valve distortion and affect the internal working parts.

Do not use PTFE tape as it may cause thread galling to occur.

Use an appropriate pipe compound, on the male threads of the internal valve and pipeline. Pull the valve into the coupling hand tight and then wrench tighten it for approximately two additional turns. Larger size valves may require an additional amount of torque to obtain a leak-free connection.

Keep piping from the valve outlet to the pump full size and as short as possible with a minimum number of bends. Reduction in pipe size to suit smaller pump inlets should be made as close to the pump as possible using forged reducers (swage nipples) or venturi tapers rather than bushings. This assures minimum flow resistance and efficient pump operation.

LIMITED BLEED

The valves have a break off section below the inlet pipe thread which is intended to permit the lower valve body to shear off in an accident, leaving the valve seat in the tank. The break off section is designed for container

installations and will probably not provide shear protection if the valve is installed in a pipeline.

A hydrostatic relief valve does not need to be installed adjacent to the valve since the internal valve relieves excessive line pressure into the tank.

Selectively Filling Manifolded Tanks

Fisher® internal valves provide positive shutoff only in one direction, from out of the tank to downstream of the valve. The

internal valves are designed to allow gas to ow into a tank

when the downstream line pressure exceeds tank pressure. If

you want to selectively ll one or more of the other tanks in a

tank manifold system, you must place a positive shutoff valve downstream of the internal valve, otherwise, all tanks will be

lled at the same time and at about the same rate.

Actuators

The remote operating control system for the valve is extremely important and it must be installed to conform with the applicable codes. DOT MC331, for example, most generally applies for trucks.

Fisher offers both cable controls and pneumatic actuator systems to operate the C470 and C486 Series internal

Types C471, C477 and C486

valves. It may also be possible to use cable controls from other manufacturers or to fabricate a linkage mechanism.

Any control system requires thermal protection (fuse links) at the valve, at the remote control point and, if necessary, near the hose connections. The Instruction Manuals for Emerson™ actuator systems show how to install the fuse links.

Installation instructions on Fisher® Types P650, P163A and

P164A cable controls, are in Document D450012T012.

Pneumatic actuator installation is covered in Document

D450162T012. Type P340 latch/remote release instructions are on Document D450123T012.

The operating linkage must allow the operating lever to

move from the fully closed position to within 2° of the fully

open position. The linkage should not apply strong force to the lever past the fully open position or the valve could be damaged.

Warranty Note

The use of non-Fisher actuators will void internal valve warranty and may result in leakage of the gland packing caused by premature wear. In addition to premature wear, the use of non- Fisher actuators may

result in lower than expected ow rates and

possible leakage across the valve seats.

CAUTION

The internal valve’s closing spring is not designed to overcome drag in the control linkage in order to close the valve. Depending upon the control system used, an external spring (such as Fisher drawing number 1K4434) or positive closing linkage may be needed. Be sure the control system is installed to prevent binding that could cause the valve to stick in the open position.

Excess Flow Operation

The internal valve contains an excess ow function or “integral excess ow valve”, that will close when the ow exceeds the ow rating established by Fisher. Fisher integral excess ow valve installed on a bobtail truck or transport

can provide protection against the discharge of hazardous materials during an unloading operation of a bobtail truck or transport in the event that a pump or piping attached directly

to the internal valve is sheared off before the rst valve, pump or tting downstream of the internal valve, provided that the cargo tank pressure produces a ow rate greater than the valve’s excess ow rating.

Likewise, if the internal valve is installed on a stationary tank or in the related downstream piping system, the

integral excess ow valve can provide protection against an

unintentional release of hazardous materials in the event

that a pump or piping attached directly to the internal valve is

sheared off before the rst valve, pump or tting downstream of the internal valve, provided that the ow of product through

the internal valve reaches the rated ow specied by Fisher.

EXPLOSION HAZARD

Restrictions incorporated in the discharge system of a bobtail truck or transport or of a stationary tank (due to pumps, pipe and hose length and dimensions, branching, elbows, reductions in pipe diameter or a

number of other in-line valves or ttings),

low operating pressure as a result of ambient temperature or a partially closed valve downstream from the integral excess

ow valve, can restrict the rate of ow

through the internal valve below the level necessary to actuate the integral excess

ow valve. Therefore, DO NOT USE the excess ow function of the internal valve for

the purpose of providing protection against the discharge of hazardous materials in the event of a rupture of hose or piping at a point in the discharge system downstream

from the rst valve, pump or tting

downstream of the internal valve.

The internal valve is designed with an internal bleed feature for equalization of

pressure. After the integral excess ow valve

closes, the leakage through the bleed must be controlled or a hazard can be created. For this reason the operator must be familiar with the closure controls for the internal valve and must close the internal valve immediately

after the integral excess ow valve closes.

Failure to follow this warning could result in serious personal injury or property damage

from a re or explosion.

DOT Passive Shutdown Equipment Requirement—DOT

regulations 49CFR§173.315(n)(2) require certain cargo

tanks transporting propane, anhydrous ammonia and

other liqueed compressed gases to be equipped with

passive emergency discharge control equipment that will

automatically shutoff the ow of product without human

intervention within 20 seconds of an unintentional release caused by complete separation of a delivery hose. The design

for each passive shutdown system must be certied by a Design

Certifying Engineer (DCE) and all components of the discharge system that are integral to the design must be included in the

DCE certication. The DCE certication must consider any specications of the original component manufacturer.

In the case of downstream ruptures in hose or piping, a variety of operating conditions routinely encountered during

an unloading operation restrict the rate of ow through the integral excess ow valve and make such a valve unsuitable

to serve as the means of passive shutdown required under

49CFR§173.315(n) (2). Such variables include restrictions

Types C471, C477 and C486

incorporated in the discharge system (due to pumps, pipe and hose length and dimensions, branching, elbows, reductions in pipe diameter or a number of other in-line

valves or ttings), low operating pressure as a result of

ambient temperature or a partially closed valve downstream

from the excess ow valve. Due to the variety of conditions,

in the case of a hose separation, that can restrict the rate of

ow below the level necessary to activate the excess ow valve, the integral excess ow function of Fisher® “C” Series internal valves or “F” Series excess ow valves cannot be

used to satisfy the passive shutdown equipment requirement

under/in 49CFR§173.315(n)(2). Also, a Design Certifying Engineer cannot include the integral excess ow valve of a Fisher “C” Series internal valve or “F” Series excess ow

valve as a component of the discharge system in any DCE

certication under 49CFR§173.315(n)(2).

EXPLOSION HAZARD

DO NOT USE the excess ow function incorporated into Fisher “C” Series internal

valves or “F” Series excess ow valves to

satisfy the passive shutdown equipment requirement in 49CFR§173.315(n)(2). DO NOT

include the excess ow function incorporated

into Fisher “C” Series internal valves or

“F” Series excess ow valves in a DCE certication under 49CFR§173.315(n)(2). The

cargo tank manufacturer must install some

other equipment that satises the requirement

for passive shutdown capability under 49CFR§173.315(n)(2).

Failure to follow this warning could result in serious personal injury or property damage

from a re or explosion in the event of an

unintentional release of product during an unloading operation.

Operation

Since the C470 and C486 Series will not open unless the downstream pressure can build-up to equal the inlet pressure, an operating sequence that assures equalization is important.

Follow these points:

1. C470 and C486 Series on bobtails and transports should never be open when the truck is in motion. If the control system is not interlocked to prevent this, the operator is responsible to see that the valves are closed.

2. Always open the internal valve before opening any other valves in the line or starting the pump.

3. Move the lever to the half-open position (Operational Schematic, view #2) to equalize pressure. When the main poppet clicks open, move the operating lever fully open.

4. Open other line valves slowly to avoid sudden surges which could slug the excess flow valve shut.

5. If the excess flow valve does close, stop the

pump and close the nearest downstream valve. Move the internal valve’s operating lever back to the rapid equalizing position and wait for the valve to click open. Then move the operating lever fully open and slowly open the downstream valve.

6. All valves should be completely open when pumping. (Throttling type valves could prevent the excess flow valve from closing when required.)

7. The operator must always be aware of where the remote closure controls are located and know how to operate the controls if an emergency requires valve closure. When pumping is finished, make a habit of closing the internal valve from the remote closure point, thus checking to see that the control actually is capable of closing the valve.

8. The valve should be open when backfilling through the valve to fill the tank.

Troubleshooting

Internal Valve Will Not Open—This could be due to leakage

downstream, engaging the pump too soon or from excessive wear in the internal valve. If excessive volume is in the downstream system, a longer time is required to equalize the pressures (tank and downstream) before the pump can be engaged. To determine if the valve pilot seat is opening, install a gauge downstream of the valve, operate the valve actuator; if pressure does not build up to the tank pressure, the valve pilot seat is not open. This test should be done with pump off. If the pilot is not opening, it may be plugged with dirt or some internal part may be broken. If by operating the lever manually it can be rotated past the fully open position, there is something wrong internally and the valve must be disassembled.

Premature Valve Closure—This can be caused from engaging

the pump too soon, by an underrated excess ow valve spring

or by an improperly connected internal valve operating lever which does not fully open the valve. The trouble could also be from a valve that has its inlet port obstructed or from sudden line surges. In order to check the valve opening travel, operate the lever manually to the full travel, wait until valve opens,

then engage the pump. If the excess ow closes, the points

mentioned above should be investigated.

Internal Valve Will Not Close—The stub shaft could be binding or the stem could be bent in the valve. Before disassembling the valve, check the actuator mechanism to see that it operates freely by disconnecting it from the valve lever and cycling it several times. Also, operate the valve lever manually. If it sticks in the open position, the packing and bushings should be replaced. This should free the operating mechanism if the valve has not been damaged internally. Refer

to the “Maintenance” section.

Low Flow Capacity—This could be caused by too small an internal valve, too small or long downstream piping, plugged screens, some other restriction in the downstream system or by the bypass valve sticking in the open position. The bypass valve could also be set too low and be opening prematurely.

Types C471, C477 and C486

the internal valve. If piping is cold allow it to warm to ambient temperature.

b. Refer to CFR 49 Section 180 Appendix B for Meter

Creep Test Methods.

3. All operating controls should be inspected and cleaned

and oiled. The controls should be checked to see that they fully open—but not over-travel—the internal valve operating lever and operate freely to close the valve.

4. Standard construction internal valves must

be removed if the container is to be steam cleaned. Heat can damage the valve’s seats and seals.

5. Standard construction internal valves are not designed

for water service. Immediately after a container is hydrostatically tested, remove all water and allow the container to thoroughly dry out.

Assembly (key 2) to Align Disc Retainer (key 8)

Maintenance

CAUTION

Do not use these internal valves if they leak, fail to work properly or have been damaged or have missing parts. Prompt repairs should be made by a properly trained service person. Continued use without repair can create a hazardous or injurious situation.

A simple preventative maintenance program for the valve and its controls will eliminate a lot of potential problems.

Fisher® recommends these steps be conducted once a month. Also refer to the Department of Transportation (DOT) CFR 49 Sections 180.416 and 180 Appendix A and B which specify monthly maintenance and inspections tests for cargo tank service internal valves and their actuation controls.

1. Inspect the operating lever to see that it operates freely and that there is no leakage around the retainer nut. If there is sticking or leakage, replace the packing and bushings. Refer to Replacing Packing.

2. Check for tight closure of the seat discs. Any detected

leakage, which is normally caused by disc wear or dirt, scale or debris embedded in the disc, requires that the internal valve be removed from service and repaired. Repair most often requires the replacement of valve discs. To check for leakage:

a. Close the internal valve and exhaust downstream

pressure. Close the rst valve downstream from the

internal valve and note any pressure buildup, using a pressure gauge, between the closed valve and

WARNING

Tank pressure must be released before removing the valve from the container. Failure to do so could result in personal injury.

Numbers in parenthesis refer to key numbers in Figures 3 to 7.

To Replace Packing or Install Gland Hardware

WARNING

Downstream pressure must be released before removing the screws holding the gland assembly to the internal valve body. Failure to do so could result in personal injury.

1. The packing (keys 15F, G and H) can be replaced with product in the tank by closing the operating lever (key 18) and blowing down the downstream pressure in the system.

2. If using Screw-Type hardware, remove the three cap screws (key 17) holding the bonnet assembly to the body. If using the current Stud-Type hardware, remove the

nuts (key 59) and washers (key 55) holding the bonnet

assembly to the body.

Note

If working on a valve equipped with a pneumatic actuator, please refer to the corresponding actuator Instruction Manual for proper removal procedures.

3. Rotate the entire bonnet assembly slightly to remove it from the body.

4. Unscrew the cap screw (key 15R) from the stub shaft

(key 15J) and remove the operating lever by taking out

the cotter pin (key 19).

5. Unscrew the retaining nut (key 15M) from the bonnet. Pushing on the stub shaft (key 15J) will expose the bonnet

parts including the packing.

6. Besides the packing, the liner bushings (keys 15B and 15K) should be replaced. Lubricate the packings with Multipurpose PTFE lubricant.

7. Reassemble in reverse order. Replace cap screw (key 15R)

using 30 to 35 inch-pounds / 3.4 to 4.0 N•m torque.

8. Before replacing the gland assembly, replace the O-ring (key 16) with the proper material matching the main seals. The standard Types C471 and C477 material is Nitrile (NBR).

9. Orient Cam and stub shaft (See Figure 4)

Before reassembling the gland assembly into the body,

make sure the operating lever can move freely with the new parts installed. Then, correctly orient the cam to the stub shaft. Incorrect orientation will result in either:

a. Not being able to open the internal valve or

b. Only being able to partially open the internal valve

which will cause the valve’s excess ow feature to

close prematurely

Refer to Figure 4. Looking at the end of the stub shaft (C)

that the lever or actuator attaches to:

1. The cam prole on the opposite end of the shaft should

be up and the cam pointing to the left.

2. The hole (B) through the stub shaft that the lever/

actuator attaches to should be oriented in a NE to SW position with N being at the top.

3. The 2 gland wings should be at the top as shown

in Figure 4.

4. The lever should be oriented as shown and the cotter pin

run through hole (B).

4. Unscrew the screws (keys 9 and 4 for 2-inch / DN 50,

6 for 3-inch / DN 80) holding the disc retainer (key 8) to replace the main seat disc.

5. Examine both seat discs (keys 7 and 11) and replace if necessary.

6. If the excess ow spring (key 3) is changed, replace the

nameplate or stamp the body with the new type number.

7. Always replace the sealing washer (key 23).

8. a. Reassemble in reverse order. Tighten the screws

(key 9) using 20 inch-pounds / 2.2 N•m torque to

install the disc retainer (key 8) properly.

CAUTION

Failure to properly center the disc retainer to the disc holder may result in improper function of the valve.

Important

During replacement of the seat disc, use P/N GE45079X012 provided to center the disc retainer to the disc holder (See Figure 3). Line up holes and insert screws. Keep the alignment tool inserted until all of the screws

are tightened to specication.

Alternately, the stem assembly (key 2) and spring seat (key 4) may be used as shown in Figure 3 to perform this alignment. After assembly, check to make sure there is no interference of the spring seat and disc retainer

when the valve is in the excess ow position.

b. Apply Medium-Strength Threadlocker on the stem

threads before installing the hex nut (key 13).

10. Once proper orientation of the cam is conrmed:

a. Reinstall the washers (key 55) and nuts (key 59) and

torque to 90 to 100 inch-lbs / 10 to 11 N•m. Reinstall

actuator or latch if applicable.

b. If reusing the cap screws, reinstall the actuator or latch if

applicable before installing the cap screws and washers.

Torque to 90 to 100 inch-lbs / 10 to 11 N•m.

c. If installing new studs, install the long studs (key 57) in

the top-most hole locations and the short stud (key 58) in

the bottom-most location. Secure the gland to the body

with the rst set of washers (key 12) and nuts. Reinstall

actuator or latch if applicable or cover two long studs with protective cap (key 60) if available.

To Replace Seat Discs

1. Remove the valve from the tank.

2. Remove the cotter pin (key 14, Figure 5) and unscrew

the hex nut (key 13).

3. Remove both disc holders (keys 6 and 12) from the stem (key 2).
