6. Push the stem out through the body bore to access both

stem seals and remove them.

7. Inspect the ball for any signs of damage or wear, if it

has either, consult the factory for a replacement.

Assembly Instructions:

1. Ensure that you have the correct repair kit for the

pressure rating of the valve.

2. Ensure that all parts are cleaned before assembly.

3. Place the stem seal (5) onto the stem (4) being careful

not to damage it.

4. Insert the stem through the stem hole from inside the

valve bore and push firmly into place. Put the top

seal (7) onto the stem and fit the spacer (14) and the

lever handle (10) in that order, then apply the nut

(12) carefully so as not to cross thread it. This can be

tightened to hold the parts in place.

5. Place the valve seat (6) into the bore on one side,

make sure that the flat face is pointing away from the

center of the valve.

6. Repeat (5) for the opposite side after inserting the ball

ensuring that the stem tongue is fitted into the slot on

the top of the ball. Then turn the handle 90 degrees to

ensure engagement and to hold the ball in place.

7. Place the new body seal ring (8) onto each end

connector (2) and insert into the valve body and with

the ball in the closed position, tighten up the end

connectors to a torque of 220Nm on both sides.

8. Finally adjust the handle nut so as to stop any leaks but

without overtightening so as to cause excessive torque

for turning the valve.

Notes:
Valves fitted with a pointer handle DO NOT have the spacer

(14) fitted and this part of the step can be ignored in the

assembly instructions.
