Description
–
The VR-801 Vacuum Relief Valve is designed to protect hot water supply systems and pressure vessels against negative pressure. It is especially well suited for many domestic and commercial systems.
It works by preventing internal vacuum conditions that could result in burned out heaters and/or collapsed storage tanks. Installed on the cold water supply line, the Cash Acme VR-801 closes tightly under pressure and opens at a 1" mercury vacuum. Atmosphere admitted to the system breaks the vacuum, preventing collapse of the storage tank.
Application:
For protection of commercial hot water supply systems and pressure vessels against negative pressure.

Spec is wrong, but good return policy
Specification says the breaking pressure is 1" Hg (so.. 24.5 mmHg or 0.5 PSI). Weird way to specify it but whatever. I found to my dismay that the breaking pressure is MUCH higher than this, on all 3 units I ordered. The return policy handled my return well, however.

Well Made Valve at the right price
I bought this vacuum relief valve to add to my expansion tank. There are no plastic pieces of brass, highly recommend well-made, and the price is right.
