Professional PA Air Release Valve from China
TREX is a specialist manufacturer of PA air release valves for irrigation, water distribution, and fluid handling systems. Based in China, we combine in‑house design, precision injection molding, and rigorous testing to deliver lightweight, corrosion‑resistant valves that automatically release trapped air, stabilize pressure, and protect pipelines from water hammer.
Advantages of PA Air Release Valve
- Automatically releases trapped air to prevent air pockets and water hammer, stabilizing pressure and protecting pipelines and equipment.
- Corrosion- and scale-resistant PA (nylon) body with UV stabilization for long, reliable outdoor service.
- Lightweight yet impact-resistant; easier handling and less stress on plastic manifolds versus metal valves.
- Broad chemical compatibility for fertigation and reclaimed/treated water; no rust contamination.
- Low maintenance with resilient seals, low cracking pressure, and reliable reseating for leak-tight operation.
