Combination Air Release and Air/Vacuum Valve

Multi-function

Combination air valves consist of an air/vacuum and an air release valves in a single housing. It is designed to exhaust large amounts of air during filling, to release small amounts of accumulated air during operation and to admit large amounts of air upon impending vacuum during draining.

The air/vacuum portion with 316 stainless steel spherical float is designed to exhaust air up to sonic velocity without blowing shut.

Combination air release and air/vacuum valves are well-suited for use on deep well turbine pumps and are installed between the pump and the discharge check valve.

 

Throttling valves provide adjustable control of the pressure at which air is discharged during filling.

Cast iron body has stainless steel internals and Buna-N seats. Working pressure is 150 psi. For sizing, refer to the tables listed for air release valves and air/vacuum valves in this section.

Larger sizes through 12" are available.
