Conventional Safety Relief Valve
This is a kind of safety valve, which is characterized by quick opening. Its structure is very reliable. Depending on the application, it will gradually open as the pressure rises. It can be used both gas and compressible fluids. Note: the set pressure of this conventional safety relief valve will be affected by superimposed back pressure and built-up back pressure in discharge system.
