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

1. Lightly oil ring groove.
Grease and insert a ring joint
into the body ange.
5. Tighten the hex nuts on the test
ange 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 ange
to the body ange.
6. A nished ange shown.
8. Remove the grease tting cap
from one test ange and attach a
pressure release tool.
7. Repeat steps 1-5 for the opposite
ange.
9. Remove the grease tting cap
from the opposite test ange and
attach the ow line.
TEST PROCEDURE
2. Be sure that the test ange has
a tightened grease tting, all of its
studs, and a nut on each with all of
the nuts on the grease tting side.
3. Align the test ange studs with the
body ange holes. Then, push the
test anges, its studs, and their hex
nuts onto the body ange.

2. After removing the body ange
hex nuts, you can remove the test
ange, its studs, and their hex nuts.
1. While holding the hex nuts on the
body ange, loosen each of the test
ange 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 tting cap, and attach a ow line from the grease pump to the bonnet grease tting.
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 ow and pressure release connections, bleed off the new pressure
release side, and repeat steps above to perform a seat test on the new ow side.
The valve is acceptable if no leakage is visible during the holding period.

2. Be sure the Alemite ttings are on
and tight.
1. Be sure the bonnet grease tting
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 ange
hex nuts with a certied
torque gun or wrench until tight.
3. Screw a hex nut on both
sides of each stud by hand.
5. A nished ange should appear as
shown.
2. Align the service ange holes with the body ange
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 ange.

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 rmly 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.

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.
