Combined Air Release Valve

Warranty period: 1 year

Valve type: Pneumatic vacuum relief valve/combined air valve

Material: Polyoxymethylene

Packaging: Carton or as required by customers

Power: Hydraulic

Type: Air and vacuum safety valve

Features:

(1) Suitable for various irrigation networks and operating conditions. It adopts advanced pneumatic design, double orifice plate and surge to effectively release cavitation in the system during pipe filling, continuously release a small amount of air during pipe pressurization, and achieve large flow intake to avoid vacuum formation when the pipe network is drained.

(2) Large flow rate. The flow passage adopts large-diameter automatic flow hole, which is suitable for flow rates larger than general flow rates.

(3) Good sealing. Dynamic sealing prevents leakage under low pressure (0.1bar/1.5psi).

(4) Small injection volume. Due to the excellent structure of the air inlet and outlet channels, the amount of water injected during automatic exhaust is reduced. Anti-clogging: The outlet adopts a backwash structure, which is not easy to scale and can adapt to different water qualities.

(5) Reliable and durable. Made of high-quality raw materials, it is resistant to corrosion, chemicals and fertilizers, requires less maintenance and has a longer service life.
