Air Release Valves–Waste Water
Air & Vaccum
Air and Vacuum valves are designed to exhaust large amounts of air on system start-up and permit equally large volumes back into the system on shut-down or vacuum formation.
SL (A), S (A), SVR, and AX Series
Pressure Air Release
Pressure Air Release Valves allow air to be continually exhausted in small amounts during the entire pumping cycle. PRVs take over when Air & Vacuum valves are closed and under pressure.
SL, S, and PX Series
These valves perform the function of both Air & Vacuum and Pressure Air Valves, permitting the application of various pressure orifice sizes for a range of air volume requirements under varying pressures.
US, USL, and UX Series
