6. Precautions for selection and use

Fluid compatibility: Select valve body material (such as copper, stainless steel) and sealing material (such as NBR, FKM) according to the type of media (such as water, oil, gas).

Pressure and flow: Ensure that the valve rated pressure and flow meet system requirements and avoid leakage or damage caused by overload.

Environmental conditions: In high temperature, humid or explosive environments, protection level (such as IP65) or explosion-proof (ExdIIBT4) products must be selected.

Electrical parameters: Match the control power supply (such as AC220V, DC24V) and response time (usually ≤50ms) to ensure compatibility with PLC or other controllers.
