DISASSEMBLING THE VALVE

1. Operate the valve to insure no trapped pressure is present.

Leave the gate set partially open.

2. Unscrew and remove the Handwheel Nut using a wrench.

Remove the Handwheel Bolt and the Handwheel.

5. Remove the Bonnet Sub-Assembly4. Replace the Handwheel and rotate it in the counter-clockwise direction. This will separate the Gate from the

Stem. 6. Remove the Gate.

8. Remove the Retainer Plates and Seats.7. Remove the Gate Guides. 9. Remove the Body Bushings.

3. Unscrew and remove all Bonnet Bolts using an impact wrench.



Page 10

DISASSEMBLING THE BONNET SUB-ASSEMBLY

2. Remove the Shear Pin from the Stem Adapter.

1. Unscrew and remove the Bearing Cap. 3. Remove the Stem Adapter.

5.Remove the Stem.4. Unscrew and remove the Packing Gland.

6. Remove the Stem Packing with a pick. Avoid scratching the internal

wall of the Bonnet during removal of the packing.

NOTE: Replace non-metalic seals while assembling the valve.



Page 14

1. Lightly oil ring groove. Grease and insert a ring joint

into the body flange.

5. Tighten the hex nuts on the test flange side with an impact wrench

until they are tight.

4. Screw a hex nut on the vacant side of each stud until all of the studs

have a nut connecting the test flange to the body flange.

6. A finished flange shown.

8. Remove the grease fitting cap from one test flange and attach a

pressure release tool.7. Repeat steps 1-5 for the opposite

flange.9. Remove the grease fitting cap from the opposite test flange and

attach the flow line.

TEST PROCEDURE

2. Be sure that the test flange has a tightened grease fitting, all of its studs, and a nut on each with all of the nuts on the grease fitting side.

3. Align the test flange studs with the body flange holes. Then, push the

test flanges, its studs, and their hex nuts onto the body flange.



Page 15

2. After removing the body flange hex nuts, you can remove the test

flange, its studs, and their hex nuts.

1. While holding the hex nuts on the body flange, loosen each of the test

flange hex nuts.

3. Pass a drift mandrel through the valve bore after the valve has been assembled, operated, and pressure

tested.

4. Remove the bonnet grease fitting cap, and attach a flow line from the grease pump to the bonnet grease fitting. Grease until any remaining water from testing drains from the valve.

HYDROSTATIC SEAT TEST

• With the valve closed, apply the rated working pressure.• Hold and monitor at that pressure for at least (3) minutes.• Open the valve, and bleed off the pressure until it’s reduced to zero. Then, close the valve

and the pressure release tool.• Repeat the steps above.

Switch the sides of your flow and pressure release connections, bleed off the new pressure release side, and repeat steps above to perform a seat test on the new flow side.

The valve is acceptable if no leakage is visible during the holding period.



Page 16

2. Be sure the Alemite fittings are on and tight.

1. Be sure the bonnet grease fitting cap is on and tight.

3. Be sure the Hand wheel Nut is tight.

4. The gate must be fully open (shown) or fully closed.

VISUAL INSPECTION

4. Torque the service flange hex nuts with a certified

torque gun or wrench until tight.3. Screw a hex nut on both sides of each stud by hand.

5. A finished flange should appear as shown.

2. Align the service flange holes with the body flange holes. Push a stud through each aligned

hole until there is a stud through each hole. 1. Lightly oil ring groove.

Grease and insert a ring joint into the body flange.

FIELD HOOK-UP INSTRUCTIONS



Page 17

CAUTION:

Never remove packing gland while valve is under pressure unless the pressure has been isolated.

1. Unscrew and remove the Handwheel Nut using a wrench.

2. Remove the Handwheel Bolt and the Handwheel.

REPLACING BROKEN SHEAR PIN (WHILE IN SERVICE)

3. Unscrew and remove the Bearing Cap.

Note:a) If Bearing Cap tries to remove the packing gland hit the stem adapter firmly to break any gunk build up.b) If the Bearing Cap will not remove without unthreading the packing gland, then pressure must be removed from the valve or the valve MUST be back seated.c) Once Bearing Cap is free or Valve is back seated go to step 4.

4. Once Bearing Cap is removed, replace damaged shear pin.

5. Retighten packing gland with pipe wrench (~100 ft*lbf)

Note: Debur with sandpaper if needed.

6. Retighten bearing cap with pipe wrench (~100 ft*lbf)

Note: Debur with sandpaper if needed.



Page 18

WARNING:

1. The backseat is only intended to be used in an emergency situation to stop packing leakage.

2. One of the features of the back seat is to change the stem packing under pressure on well, even though it is not promoted. It is always recommended that the valve be removed from service before packing is changed unless an emergency. If the packing has to be changed while under pressure, a second pressure barrier needs to be used to help isolate the pressure.

3. By backseating the valve it is possible the gate will not seal the bore line.

2. Loosen the bearing cap using a pipe wrench.

(Approximately 3 1/2 - 4 turns)

1. Turn the handwheel counter-clockwise until the gate is in the

open position.(In case of Direct Operating gate)

3. Turn the handwheel clockwise until the gate is in the closed

position.

BACK SEATING PROCEDURE

4. Over run the closed position such that the gate hits the bottom and

rises the stem; which jams the back seat area.
