The security of the pneumatic valve opening pressure

the pneumatic valve opening pressure of the initial opening pressure and opening pressure of the points, in the security after the closing of the pneumatic valve sealing loss, pneumatic disc to the medium pressure rises is the initial pressure. When the full open and large discharge medium pressure is known as a full opening pressure. Usually called initial opening pressure safety pneumatic valve opening pressure. All pneumatic valve opening pressure is called safety discharge pressure. Security of the pneumatic valve opening pressure is lower than the design pressure of the pressure vessel.
