Air relief valve DUOJET®-P

for water systemsstainless steelcast iron

40% higher performance than standard air valves: High-capacity, single-chamber air valve with triple function for venting and releasing air in pipelines as well as for releasing air during operation. Corrosion-proof due to stainless steel inner parts and float made of plastic. Safe and reliable operation even at high air-release velocities of up to sonic speed. Suitable for use in water treatment, water distribution, in dams, power plants and in industry. Sealing system/standard: Resilient seated Single chamber air valve in compact design Very high discharge capacity up to sonic velocity due to stabilised floater Venting function: Small orifice to release low quantities of air during operation under pressure Large orifice to vent high quantities of air during draining the pipeline Large orifice to release high quantities of air during filling the pipeline Outlet female threaded: acc. to DIN ISO 228 With flange end acc. to EN 1092-2 Minimum operation pressure: 0.3 bar The full-bore design with nominal diameter equal inlet, passage and outlet flow area increase the performance about double higher than the standard Duojet valve. with integrated ball valve Triple function air valve
