Air Release Valves – Waste Water

Air Valves

Air & Vacuum

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

Combination

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
