The standard is suitable for the multi function pump control valve 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 &mdash of the material of the shell, the inner part and the control pipe system; the temperature level is determined by the &mdash. The maximum allowable working pressure of the multi-function pump control valve at a certain temperature takes the small value of the maximum allowable working pressure of the material in the shell, internals and control pipe system under this temperature.
