Safety valves made of stainless steel, atmospheric discharge, with threaded connection

Our smallest and most compact atmospheric discharge safety valve made completely of stainless steel with a stainless steel spring. Due to the huge blow-off capacity compared to its size, this valve can be used to protect high-performance compressors.
This safety valve is also ideally suited for the protection of large stainless steel pressure vessels and air systems made of stainless steel in aggressive environments or in clean-service areas.
