2" Plastic Air Release & Vacuum Relief Vent
Prevent costly air-lock blockages and vacuum-induced pipe collapse with this 2" simple-action air release and vacuum relief vent. Designed for commercial irrigation systems, this valve automatically expels trapped air during system startup and admits air during shutdown to prevent damaging negative pressure. The 2" MNPT inlet connection makes installation quick and compatible with standard irrigation fittings.
