About this item

  • PA Material: corrosion-resistant, acid and alkali resistant, long service life
  • Large Inlet and Exhaust Port Size, High Flow Rate : The valve body adopts the gas dynamics of the DC channel design
  • Dual-exhaust Port Design: power fast exhaust port and micro-automatic exhaust port, which can continuously exhaust the gas generated in the pipeline
  • Power Low-pressure Sealing - can maintain good sealing at low pressure (0.3bar) to avoid leakage phenomenon
  • Application: System Piping - Prevents air from accumulating at high points of the pipeline, slope inflection points, road and river crossings, eliminating negative pressure. Water supply system-Prevent air from accumulating and eliminate negative pressure. Industrial system pipe network and residential area pipe network - to prevent air accumulation


Compact Air Valve for Water Systems Resolves air/vacuum issues in water supply & filtration systems during filling/draining. Aerodynamic design ensures low-pressure sealing with 280m³/h air exchange. Certified for 15 bar pressure. Key Features - Anti-blowing float prevents premature closure - Auto micro-exhaust releases trapped air - Vacuum-breaker during drainage - NPT connections for universal compatibility Applications Irrigation Pipelines - Prevents vacuum at pumps/pipe slopes Filtration Stations - Vents air from filters/fertilizer tanks Elevated Pipes - Eliminates air pockets causing pipe bursts Pump Stations - Boosts efficiency + reduces power outage surges Field Systems - Protects water meters & pressure regulators Smart 3-Stage Operation 1.Filling: Rapid air discharge → Float seals port upon water entry 2.Pressurized Use: Auto vents accumulated air via micro-port 3.Draining: Opens instantly to break vacuum Tech Specs Caliber: NPT Pressure: 0.35bar sealing / 15bar max Flow: ±280m³/h @ ±0.35bar

I’ve been using this air relief valve in my irrigation system, and it works great. The corrosion-resistant PA material ensures long-lasting durability, even in harsh conditions. The dual-exhaust port design effectively eliminates air buildup, preventing negative pressure in the pipes. It’s easy to install with its NPT threaded interface, and I’m impressed by how well it seals at low pressure, ensuring a leak-free experience. Perfect for both residential and industrial use!
