Product details
Val-Pak V20-322 is the compression ring for Purex SM and SMBW 2000 series backwash valves.
Where it sits
The compression ring carries the clamping load inside the valve. As the valve is drawn down, the ring is what keeps steady pressure on the sealing surfaces, so a ring that has cracked or deformed shows up as a valve that will not seal no matter how far it is tightened.
Doing the job once
Getting to this ring means opening the valve, which is the same access needed for the rotor and its seal. Look at those while the valve is apart rather than going back in a season later.
