Compressed air safety-valve

Compressed air is air that has been condensed in a compressor. Pressure safety valves can secure containers and pipelines operating under pressure. As soon as the pressure within the container reaches or exceeds the pressure set in the pressure safety valve, the valve opens and releases the compressed air. This reduces the pressure within the system.
We set the pressure value on the pressure safety valve according to your wish before sealing the valve. The pressure safety valve reaches its maximum hub (valve completely open) once the pressure exceeds the set pressure value by 10% and closes once the pressure falls 10% below the set pressure value (20% for liquid media). The tolerance is +/-3%.
The pressure safety valve is marked with D/G. This indicates a free scrubbing valve, meaning that the excess compressed air is released into the surrounding. As a result, pressure safety valves should be used only with safe media.
To monitor and service the valve, it comes with a twist-type lifting mechanism. This lifting mechanism needs to be used regularly in order to prevent pollution, which could damage the pressure safety valve.

Huge variety of pressure safety valves for compressed air

Pressure safety valves are used to protect pressure vessels, compressed air systems and compressors producing compressed air. Pressure safety valves from NieRuf can withstand a response pressure from 0,2 to 350 bar, depending on the build. If required, we can also offer pressure safety valves made of stainless steel or brass with a FKM or metallic seal. FKM seals are especially useful in applications with oily media. All valves are available with an external thread ranging from ¼” to 2”. We can also deliver your pressure safety valve TUV approved.

compressed air safety valves at low cost

We can have your pressure safety valve designed, build, sealed and shipped in only a few days. Order your pressure safety valve from our online shop, or send us an email. Need more help? Please do not hesitate to contact us through our free hotline.
