Standard technical requirements for multifunctional pump control valves
This standard is applicable to multifunctional pump control valves with nominal pressure of PN1.0MPa - PN4.0MPa and nominal diameter of DN50mm - DN1200mm.
The standard technical requirements are introduced as follows:
1. pressure - temperature degree
The pressure temperature level of the multi-function pump control valve is determined by the pressure of the shell, the internals and the material of the control pipe system. The maximum allowable working pressure of a multi-function pump control valve at a temperature to take the small value of the maximum allowable working pressure value at the temperature of the shell, inner part and control pipe system material at the temperature

Definition and classification of valves
Valve is the control part of the fluid conveying system. It has functions such as cut-off, regulation, diversion, prevention of countercurrent, steady pressure, diversion or overflow pressure relief. Valves used for fluid control systems, ranging from the simplest cut-off valves to the most complex automatic control systems, have a wide range of valves and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive medium.
