air release vent valve

Air Release Valve is applied for irrigation system or networks of water supply. It evacuates air during pipeline filling and enables large volume air intake in the event of network draining, it plays important role in networks system security. Air Release Valve will allow air to escape the pipeline, thus preventing water hammer or blockage. Air Release Valve will also allow air to enter the lines as water evacuates the lines at shutdown. This prevents vacuum suction of dirty water from occurring.

C Type is a high quality combination air valve for a variety of irrigation networks and operating conditions. With its advanced aerodynamic design, double orifice and Surge, it allows efficient release of air pockets from system during pipelines filling, also release a little air continously during pipeline pressurised and enables large volume air intake to avoid the vacuum formation in the event of network draining. Features: · Large Flow: Sֺtraight flow body with large diameter automatic orifice, more than usual flow rates. · Excellent Seal: Prevents leakage under low pressure (0.1bar /1.5psi) by dynamic sealing. · Less jetting: Reduces jetting water during automatic air release as the excellent intake and exhaust channel structure. · Anti-clogging: The outlet with backwash structure is not easy to accumulate dirt, which can be suitable for different water quality. · Reliable and durable: Produced by excellent raw material which is of corrosion, chemical and fertilizer resistant, less maintenance and longer service life. Application : · Mֺain Irrigation Networks: Protection against air accumulation and vacuum formation downstream of pumps, along supply lines and at high place in main irrigation networks. · Iֺrrigation Control Heads: Protection against air accumulation and vacuum formation at filtration, and fertilization stations and downstream of main control valves. · Iֺnfield Systems: Protection against air accumulation and vacuum formation near water meters and automatic regulators. · Pֺumping stations: Maximising pumping efficiency, priming capabilities and reducing the possibility of pressure surges during power stop
