Key factors affecting differential pressure performance
Multiple factors can affect the actual pressure differential tolerance of solenoid valves:
Valve body structure design: There are significant differences in differential pressure performance between direct acting and pilot operated structures
Selection of sealing materials: Seals made of different materials have varying tolerance to pressure and temperature
Characteristics of working medium: The density and viscosity of gas and liquid affect the resistance of valve core movement
Temperature conditions: High temperature environments can reduce the mechanical strength of materials and affect their ability to withstand pressure differentials
Power supply voltage stability: Voltage fluctuations directly affect electromagnetic force, which in turn affects valve core action
