Disassembly
For valves with clamp end connections:
1. Loosen and remove the clamps connecting the valve to the piping. Then, remove the valve and gaskets.
2. Loosen and remove the hex nuts and lock washers from the bolts #14 or #14A.
3. Pull the end caps free #2 from the body.
For valves with welded end connections:
1. The valve can be disassembled with the body subassembly swung out from the end fittings or it can be
disassembled with the body subassembly completely removed from the end fittings.
2. To swing out the body subassembly from the end fittings:
i. Open the valve.
ii. Loosen the hex nuts.
iii. Remove the bolts, nuts, and lock washers between the body. Do not remove the bolt that goes through the ring
on the body.
iv. Spring the connecting piping 1/8" to remove the compression on the body from the end caps.
v. Swing the body out from the end fittings until the body completely clears the end caps. The body’s swing out
ring will rotate about the bolt.
vi. The sprung piping can now be returned to its original compression, if desired.
3. To remove the entire body subassembly from the piping, in step iii above, remove all bolts.
Continued steps for all valve end connections:
4. Remove the body seals #17 and encapsulated ball seat #4.
5. Turn the stem to close the ball. Then, slide the ball #3 out of the body #1, taking care not to nick or scratch the ball.
6. Loosen and remove the handle nut #13 from the stem. Remove the handle, lock plate, and washer #10.
7. Unscrew and remove the gland nut #13 and two spring washers #10.
8. Push the stem into the body and out an open end of the body. Remove stem O-ring #7 and thrust washer #6.
9. Remove the gland ring #9 and PTFE stem packing rings #8.
10. Remove the stopper #16 from the body.
