Bermad IR-C15-P-AU 50mm Combination High Quality Air Valve (PN10)

The Bermad IR-C15-P-AU is a premium 50mm combination air valve specifically designed for irrigation systems operating at PN10 or PN12 pressure ratings. It provides triple-function protection—relieving air during pipeline filling, releasing trapped air during operation, and admitting large volumes of air during network drainage—to prevent vacuum formation and pressure imbalance.

Its aerodynamic full-body design, large-diameter orifice, and dynamic sealing ensure exceptional air handling capacity and tight sealing under low-pressure conditions (as low as 0.1 bar). Constructed with glass-reinforced nylon and corrosion-resistant internal components, the IR-C15-P-AU is built for durability in challenging water qualities, including river, channel, dam water, and treated effluent.

Tested to meet EN-1074/4 and other international standards, it is compact, reliable, and ideal for use across irrigation control heads, mainlines, and infield systems.
