INTRODUCTION

RECEIVING &

STORAGE

Resilient Seated Gate Valves (RSGV) were

introduced in the 1980’s and became a dominant

preference for use. This manual will provide you with

the information needed to properly install, operate, and

maintain the valve and to provide long service life.

RSGVs are available as a Full Wall (FW) or Reduced

Wall (RW) resilient seated valve and comply with

AWWA C509 or C515 standards.

The RSGV contains a wedge fully encapsulated

with EPDM rubber that is permanently bonded to the

wedge and meets ASTM D249. The RSGV body, bonnet,

and stuffing plate are coated with fusion bonded epoxy

(FBE) and applied in accordance with AWWA C550 and

are ANSI / NSF 61/372 certified, or two part epoxy,

14"-24".

Optional configurations also include a Non-Rising

Stem (NRS) or Outside Screw & Yoke (OS&Y).

Inspect valves upon receipt to ensure correct

material, quantity, and any optional equipment has been

received. Also inspect all received equipment for any

damage which may have occurred during shipment.

Contact the Kennedy Valve team to report any issues

with materials received. RSGV requires no routine

maintenance except that the valve must be operated

at least once a year to prevent stem binding due to rust

and encrustation.

Unload all valves safely to protect both the

materials and workers. Do not allow lifting lugs, slings,

or chains to encounter the valve wedge seating surface

areas. Store valves indoors with the valve in the fully

closed position to prevent damage to the seating surface

by foreign material. If outdoor storage is required valves

need to be protected from weather and foreign materials.

In colder climates where freezing may occur, remove

any water from the valve interior and close valve before

storage to prevent cracking of the valve casting and

deterioration of the resilient seated EPDM.

WARNING:

Installation of valves should be performed

by experienced installers. Valves should

never be used as structural supports and

movement into place. Valves are heavy and

may include accessories or bolt on pieces

which should be handled with caution.

NOTE:

BEFORE INSTALLING THE VALVE:

1. Wipe away any dirt and grit from the inside

of the valve

2. Flush the line completely.

3. Check the operation of the valve – full open

to full closed when installing the valve.

4. Cover the valve with burlap or similar

material while backfilling to protect the

coating after installing the valve.

5. Open the valve about five turns and allow the

flow an opportunity to flush any trash and

debris from the line.

It is recommended that valves be installed into piping

system in accordance with AWWA M-11 and NFPA

guidelines to prevent any undue piping stress, deflection

or bending that may affect the performance of the valve.

1. Prior to installation, check that valve end joints

are clean. Check for damage to the valve. Open and

close valve to insure proper operation. Close the

valve before placing it in trench or line.

2. Handle valve carefully. Do not drop into position.

Do not sling through the port opening.

3. Prepare pipe ends according to manufacturer’s

instructions. Install valve per proper methods

according to end joint type. All piping should be

properly supported to avoid line stress on the valve.

Do not use the valve as a jack to force a pipeline

into position.

4. A valve box or vault should be provided for each

valve used in buried service application.

These should be installed such that no load is

transferred to the valve.

5. Before pressurization of the pipeline and valve, all

pressure containing bolting (cover, follower plate,

end connection) should be inspected for adequate

tightness (usually 90 ft. lbs.).

(CONT'D)

INSTALLATION

The operation of a RSGV is not like that of a double

disc gate valve. In normal circumstances less operating

torque is required as the resilient wedge valve just

closes, or on opening. Valve operators should adhere to

the “Turns to Fully Open RSGV” listed in the

table below.

6. Buried valves should be pressurized

before backfilling.

7. With valve in open position, the entire system should

be thoroughly flushed to clean the system. Debris in

the valve could prevent valve from closing or

possibly damage the resilient material on the wedge.

8. Upon completion of the installation, gate valve

location, size, type, date of installation, number

of turns to open, direction of opening, and any other

special information should be entered on

permanent records.

TROUBLESHOOTING

The RSGV requires no routine maintenance except

that the valve must be operated at least once a year to

prevent stem binding due to rust and encrustation.

If the valve has not been abused, the stem seal/

packing may be the only items to ever be replaced,

and instructions are included below. There have been

occasions where a wedge has required replacement

and instructions are included but this should not be

considered normal maintenance.

MAINTENANCE

OUTSIDE SCREW & YOKE (OS&Y)

Before attempting to repack the valve, first attempt

to stop the leakage by adjusting (tightening) the brass

nuts on the packing gland. Tighten both nuts snugly and

uniformly to about 60 ft-lb. The switch groove should be

above the packing when brass nuts are tightened. Verify

that the switch groove on the stem has smooth corners.

Sharp corners exist on some older valves. File as

necessary. Operate the valve a time or two to determine

if the leakage has stopped. Before beginning repacking,

contact Kennedy Valve to obtain packing (packing

supplied by Kennedy Valve may come in one continuous

coil or in segments).

OS&Y PACKING PROCEDURE

1. Operate the valve to its fully open position (apply

approx. 50 ft-lbs. torque for valves 3” and smaller,

100 ft-lbs. for valves 4” and larger)

2. Verify that the switch groove on the stem has smooth

corners. Sharp corners exist on some older valves.

File as necessary.

3. Remove the nuts [Item R8] retaining the

packing gland.

4. Lift the packing gland. If necessary, lever the packing

gland with a crowbar or similar tool. Zip ties work

well to temporarily fasten the packing gland to the

handwheel above.

5. Remove and replace the packing - (if the packing is

in multiple or individual rings, be sure to stagger the

adjoining ends from one layer to the next). We

recommend using a packing removal tool. Remove the

packing gland bolts and replace them with threaded

rods through the packing gland and place nuts on the

free ends of the threaded rods. Tighten the nuts with a

deep well socket until all leakage stops. Exchange the

threaded rods for the actual packing gland bolts/nuts

(one side and then the other).

6. Reinstall the packing gland bolts and nuts, tightening

the nuts uniformly, one side then the other so that the

packing gland pulls down evenly. Tighten the nuts

until all leakage past the packing stops. Operate the

valve through several complete open/close cycles to

check for stem binding and to be certain that there

is no leakage.

NON-RISING STEM (NRS) VALVES

Before beginning, contact Kennedy Valve to obtain:

1. Stem sealing O-rings - (2) req'd

2. One stuffing box gasket / O-ring - (1) req'd

NRS STEM SEAL REPLACEMENT PROCEDURE

1. Operate the valve to its full position (apply approx.

50 ft-lbs. torque for valves 3” and smaller, 100 ft-lbs.

for valves 4” and larger)

2. Remove the nuts retaining the stuffing box

3. Separate the stuffing box and the cap/bonnet

(the seal between the cap/bonnet and the stuffing box

may require the use of a small pry bar or a soft

faced hammer).

4. Remove and replace the O-rings. Wipe all grit and dirt

from the bore of the stuffing box and stem. Lubricate

the bore of the stuffing box, the stem, and the stem

seal O-rings before installing the stem seal O-rings.

Two O-rings on the shank of the stem and One O-ring/

gasket seal on the bottom of the stuffing box. It may

be desirable to use a small amount of a cyanoacrylate

adhesive to retain the O-ring during reinstallation.

(I.e. Permabond 910, Loctite 404, etc.)

5. Replace the stuffing box. Tighten all bolts uniformly

and carefully so that the stuffing box is flat and

snug against the cover and the gap between the cover

and stuffing box does not exceed 0.015” and uniform

(normally there should be no gap). Check the stem for

binding but operating the valve.

STEM SEAL

PROCEDURES

RESILIENT WEDGE REPLACEMENT

1. It is necessary to take the valve fully out of service

to replace the wedge, but it is not necessary to

remove the valve from the line.

2. It is very unusual to have to replace a wedge. Wedges

normally can be expected to last for many years and

thousands of cycles. Before replacing a wedge, first

check to see if the operation personnel are closing

the valve tightly. If the valve is closed tightly, open

the valve about five turns and attempt to cause the

maximum flow through the valve to flush any debris

from the seating area. If it is necessary to replace a

wedge suspect that there is some systematic problem

causing the wedge failure such as stones in the line.

3. Before attempting to replace the disc, contact

Kennedy Valve to obtain:

A. Cap/bonnet O-Ring

B. Wedge

WEDGE REPLACEMENT PROCEDURE

1. Partially open the valve.

2. Remove the cap (bonnet) bolts and nuts.

3. Lift the cap/bonnet, stem, stuffing box, and

wedge from the body.

4. Remove and replace the wedge by un-threading the

stem from the wedge nut.

5. Replace the cap sealing O-ring (not always necessary)

– Retain the O-ring with lubricating grease (Clarion

Food Machinery Grease, No. 2). Lubricate stem with

same grease.

6. Replace the cap/bonnet, stem, stuffing box, wedge

assembly– taking care to start the disc into the guides

cast into the body.

7. Place the bolts through the holes in the body and cap/

bonnet – taking care to line the bolt holes up.

8. Snug the cap/bonnet bolts finger tight and then tighten

them. First tighten two bolts diagonally opposite with

wrist torque. Then go to another bolt opposite the first

two and tighten. Then work around the bolt pattern

tightening the bolts.

9. Operate the valve fully open to fully close

before backfilling.

OS&Y PACKING GLAND

REPLACEMENT PROCEDURE

1. Remove the packing gland fasteners.

2. Remove the cap/bonnet fasteners.

3. Rotate the hand wheel in “valve closing direction”.

This action will allow the entire cover assembly

to travel upward until the threads of the yoke nut

completely disengage the threads on the stem.

4. Carefully, lift the cap/bonnet assembly [cap/bonnet

assembly includes Handwheel Hold Down Nut,

Handwheel, Upper Thrust Washer (sizes 3”thru 12”),

Lower Thrust Washer, Yoke Nut, Packing Bolts &

Nuts, Packing Gland, Packing] up and completely

off stem [item R14].

5. Remove the old packing and discard the old

packing gland.

6. Position the new packing gland into the packing well

of the cap/bonnet. The packing gland is not meant to

be secured at this point.

7. Carefully, reposition the cap/bonnet assembly over the

stem until the end of the stem contacts the starting

threads of the yoke nut.

8. Rotate the hand wheel in “valve opening direction”.

This action will allow the entire cap/bonnet assembly

to travel downward until the cap/bonnet assembly

rests on the top of the body flange. --- Make sure that

the cap/bonnet O-ring is not damaged and

is in position.

9. Bolt the cap/bonnet to the body, using an alternating

tightening pattern, assuring that the cap/bonnet is

down flush to the body (the maximum gap should not

exceed 0.015” and should be uniform (normally there

should be no gap). --- see last page for bolt

torque recommendations.

10. Refer to the OS&Y Packing Procedure.

SECTION 2B. SWITCH TRIPS PREMATURELY

(Brown / Yellow has continuity in open position)

1. If the meter reads 0 ohms resistance in the open position as in

gure 4, this indicates sthe switch is tripping prematurely

Remove the tamper plug with the 9/16” Allen key.

SECTION 2C. SWITCH DOES NOT TRIP

(Brown / Yellow fails to gain continuity when closing valve)

1. The brown / yellow circuit does not have continuity whether

the valve is open or closed. This is because the adjustment nut

must be backed o to properly contact the switch. Perform

Step 1 of Section 2b, remove the plug.

(CONT’D)

2. With the valve in the open position, insert a 9/16” socket into

the switch. Turn the nut within clockwise direction until

continuity is lost on the brown / yellow circuit. Counteract

rotation of the nut with a 9/16” open wrench.

3. Close the valve and verify that the circuit gains continuity as in

Step 3 of Section 2a.

4. Repeat steps 1-3 with yellow/orange striped wire and

brown / orange striped wire. This checks the function of the

secondary switch. If both switches function as shown in

gures 3 and 6, the switch functions properly and no further

adjustments are required.

Section 2a: No Adjustment Needed

1. Verify switch function by attaching one lead of the megohmmeter to the brown wire, and

another lead to the yellow wire. Leave the valve in the fully open position

2. Open the valve fully, if correctly set the megohmmeter should indicate no continuity. If the

meter indicates 0 resistance, the switch must be adjusted because the adjustment nut is too

far out and must tightened (see section 2b).

3. Close the valve enough to move the trip arm out of the groove as shown. The

megohmmeter should then read 0 ohms resistance.

4. Repeat steps 1-3 with yellow/orange striped wire and brown/orange striped wire. This

checks the function of the secondary switch. If both switches function as shown in figures 3

and 6, the switch functions properly and no further adjustments are required.

Section 2b: Switch trips prematurely (brown/yellow has continuity in open position)

1. If the meter reads 0 ohms resistance in the open position as in figure 4, this indicates

the switch is tripping prematurely. Remove the tamper plug with the 9/16” Allen key.

TAMPER SWITCH FIELD INSTALLATION:

1. Close valve.

2. Remove wheel nut with appropriate open end wrench.

3. Remove handwheel.

4. Screw switch unit into tapped hole until bushing is

flush with the inside of the yoke.

5. Tighten nut against yoke with an open end wrench to

50 FTLBS min.

6. Re-install handwheel.

7. Open valve until trip arm is halfway into the groove.

8. Remove security plug.

9. Using 9/16” socket with extension, back off

adjustment nut until it depresses switch tab;

counteract rotation of the trip arm with a 9/16”

open end wrench. There will be two clicks. At this

point there should be continuity through the brown

and yellow leads. The brown with orange stripe

and yellow with orange stripe leads must have

continuity as well.

10. Open valve fully, ensuring the trip arm is seated

in the groove. At this point the blue to yellow leads

and blue / orange to yellow / orange leads must have

continuity. If both switches aren’t in unison, further

adjustments must be made.

NOTE: The switch must be installed in such a manner

so that closing 20% of the valve or a maximum

of 4 revolutions will cause the switch to change

status; verify this after setting limits.
