2.The conformation of working pressure grade(pressure grades) The working pressure is the quiet pressure which the head valve received while the safety valve in general operation, it is as same as the working pressure of the protected system of equipment. The safety valves of the same nominal pressure can be divided different working pressure grades according to the spring design demands. The details are as follows.
