1) First of all, it is recommended to choose a bellows-sealed globe valve to avoid the frictional resistance of the plunger valve and the packing valve and make the switch easier.
2) The valve core and seat must be made of materials with good erosion resistance and wear properties, such as Stellite cemented carbide;
3) It is recommended to adopt a double disc structure, which will not cause excessive erosion due to small opening, which will affect the service life and sealing effect.
