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