Air Relief Valve, Vacuum and Air Release Valve for Irrigation System - NPT Threaded Interface

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

• 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
