Air Valve Family

These valves regulate air flow in pipelines to prevent collapse due to vacuum formation.

A maintenance-free, all stainless-steel valve with Air/Vac, Pres/Rel. and Combination assemblies.

Available in single or dual body styles, these valves act as both Air/Vac and Pres/Rel. Sewer valves.

These valves are the high-capacity version of our standard Combination Sewer Valves.

These valves vent air and gas in pressurized systems, while keeping solids away from working parts.

These valves are the high-capacity version of our standard Pressure Air Release Sewer Valves.

With long bodies and bottom floats, these valves vent air while keeping waste away from working parts.

These valves are the high-capacity version of our standard Air & Vacuum Sewer Valves.

A maintenance-free, all stainless-steel valve with Air/Vac, Pres/Rel. and Combination assemblies.

These valves combine Air& Vacuum and Pres/Rel. Valves to meet a variety of air venting needs.

These valves feature an Air & Vacuum Valve and Pres/Rel. Valve mounted in a single body casting.

These valves perform the function of both Air&Vacuum and Pressure Air Release Valves on a line.

Similar to the M Series, these economical valves come with one orifice rated for 300psi.

These valves are used on pressurized hot, cold and irrigation systems to vent accumulating air.

These valves vent accumulating air during the pump cycle when a system is under pressure.

These valves prevent the pump column from draining upon shutdown with a Buna-N drip-tight seal.

These valves limit the effects of system surge on Air Release Valves.

These valves control air flow during both positive & negative pressure conditions in a pipeline.

These valves help prevent chatter and premature valve closure during pump discharge.
