Bermad IR-C30-P High Quality Combination Air Valve (PN16)

The Bermad IR-C30-P is a durable and efficient combination air valve, engineered to protect pipelines and water distribution systems from the harmful effects of trapped air and vacuum formation. Designed with a double orifice aerodynamic profile, it ensures high-capacity air evacuation during filling, continuous air pocket release during operation, and rapid air intake during draining.

Certified to AS4956 / AS4020 / WSAA / MRWA standards and rated to PN16 (230 psi), this valve delivers low-pressure sealing down to 10 kPa and is suitable for a wide range of irrigation and water network applications. Surge protection (SP), inflow prevention (IP), or assisted closure (AC) kits can be added to the 50mm model, providing tailored protection in sensitive installations.

Its glass-reinforced nylon body, with optional ductile iron variants, offers long-lasting performance with corrosion-resistant internal components. A removable lower body plug enables easy integration of gauges, sensors, or drain valves.
