VAG DUOJET-T Automatic Air Valve Tamper resistant - water

VAG DUOJET®-T Automatic Air Valve. High-capacity, single-chamber air valve with triple function for venting and releasing air in pipelines as well as for releasing air during operation. Special tamper resistant strainer and bonnet design according to DIN standard. Corrosion-proof due to stainless steel inner parts (in size DN 50, inner parts 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.

PN: 10/16/25 - DN: 50...200
