Notes:
This unidirectional seal must be installed so the ring is downstream from the high pressure side of the valve at shutoff, as shown.

2. Lay the valve flat on a work bench in a secure position with the retaining ring (key 2) and retaining ring screws (key

22) facing up. Use blocks or other appropriate techniques to support the valve. Remove all retaining ring screws.

3. Remove the retaining ring by placing a retaining ring screw in each of the two retaining ring jack screw holes. With

the appropriate tool, slowly rotate the screws until the retaining ring has been lifted from the valve body.
