Test approved atmospheric discharge safety valves for industrial applications
High performance safety valves made of brass, atmospheric discharge, with threaded connection
The basic model within the range of high performance safety valves. Up to date technology and highest precision, high-quality components such as a stainless spindle and spring fitted into a slender body made of brass. This valve is suitable for air and gaseous media up to a set pressure of 40 bar, which can be freely discharged into the atmosphere.
For the protection of:
pressure tanks and
pressure systems for air and other neutral, non-poisonous and non-flammable gases which can be freely discharged into the environment
Please observe plant-specific regulations and use of appropriate valve version and sealing material.
pneumatic control units
pressure booster plants air-side
paint spray shops
transport- and railway applications
pneumatic braking systems
Safety valves are set and sealed at the factory.
