Selection of solenoid valves based on pressure parameters: principle and structure
1. Nominal pressure: This parameter has the same meaning as other general-purpose valves and is determined according to the nominal pressure of the pipeline.
2. Working pressure: If the working pressure is low, the direct-acting or step-by-step direct-acting principle must be used; when the minimum working pressure difference is above 0.04Mpa, direct-acting, step-by-step direct-acting or pilot-operated can be used.
