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.

Key Benefits

  • Dual-action protection: Expels air on pressurization and admits air on depressurization to safeguard pipelines
  • Durable & corrosion-resistant: Made from reinforced polypropylene and polyamide (nylon) for long service life in harsh field conditions
  • Weather resistant: UV-stabilized plastic construction withstands outdoor exposure season after season
  • Low sealing pressure: Seals at just 5 PSI for reliable performance even in low-pressure systems
  • High pressure rated: Handles up to 175 PSI for use on mainlines and high-pressure submains
  • Lightweight & easy to install: Plastic body reduces weight on overhead installations and simplifies handling

Applications

  • Drip and micro-irrigation mainlines and submains
  • Sprinkler system pipelines
  • Pump discharge headers
  • High points in undulating terrain where air naturally collects
