Vacuum Relief/Air Inlet Valves

Vacuum Relief/Air Inlet Valves are a normally closed valve and any time the System Pressure becomes Negative - IT OPENS IMMEDIATELY - allowing air into the system to prevent a vacuum from forming. When system pressure returns to positive, the Vacuum Relief/Air Inlet Valve closes air tight. Standard valves are designed to open with a minimal 1/4 PSI pressure differential across the orifice. Higher or lower relief settings are available to suit the application. Rated 125# class, higher pressures available.

Sizes 3" thru 36".

Also available: 1500C Combination with Air Release Valve
