Safety Valve and Back Pressure Valve

Pressure relief valve is often called as safety valve or safety relief valve, is according to the working pressure system automatic opening and closing, generally installed in the closed system equipment or pipeline protection system safety. When the pressure in the equipment or pipeline exceeds the set pressure of the pressure relief valve, the pressure relief shall be automatically opened to ensure that the medium pressure in the equipment and the pipeline is under the set pressure to protect the normal operation of the equipment and pipeline to prevent accidents and reduce the loss.

Back pressure valve is also diaphragm valve, which will make the system have steady pressure. The shape appearance is same as safety valve.But flow direction is opposite against to safety valve.The pressure adjust range is from 0.1-1Mpa.Features
