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.
