Double Orifice Air Release Valve | Ductile Iron PN16 for Water Pipeline

Our double orifice air release valve is manufactured from high‑quality ductile iron with PN16 pressure grade. This automatic air vent valve is installed on water‑supply and sewage pipelines to discharge large volumes of accumulated air while pipelines fill with water, and exhaust tiny air bubbles during daily operation. It prevents pipeline vibration, water hammer and pressure loss effectively, extending pipeline service life.

All our flanged‑type air release valves follow international industry standards, available from DN50 to DN300. Our products are widely used for municipal water‑supply projects in Syria, UAE and other Middle‑East countries, with stable performance adapting to harsh outdoor environment.
