The maximum pressure differential (the difference between the inlet and outlet pressure) which is allowed for operation. When the outlet pressure is 0 MPa, this becomes the maximum operating pressure.

The minimum pressure differential (the difference between the inlet pressure and outlet pressure) required to keep the main valve fully open.

The maximum pressure that can be applied inside the pipelines (line pressure). [The pressure differential of the solenoid valve portion must not exceed the maximum operating pressure differential.]

The pressure in which the valve must be withstood without a drop in performance after holding for one minute under prescribed pressure and returning to the operating pressure range. [value under the prescribed conditions]

A high voltage which is momentarily generated by shutting off the power in the shut-off area.

A degree defined in the “JIS C 0920: Waterproof test of electric machinery/appliance and the degree of protection against the intrusion of solid foreign objects.”

NBR: Nitrile rubber
FKM: Fluororubber - Vition?, DAI-EL?

The degreasing and washing of wetted parts.
