1. Even when using with the specification range listed in the catalog, when the IN side of the check valve is throttled, it may fail to open all the way and may generate vibration. 2. The minimum operating pressure is the pressure when the valve begins to open, and not the pressure when the valve is fully open. 3. The check valve has a construction, in which it is closed by the differential pressure generated when the inlet pressure (IN side) or outlet pressure (OUT side) solenoid valve is switched. Be aware that the check valve does not close completely and the outlet pressure (OUT side) may drop when the inlet pressure (IN side) drops gently and the differential pressure becomes smaller than the minimum operating pressure or cracking pressure. 4. It can not be sealed of valve by only built-in spring, so please use in an environment where differential pressure is generated. 5. Check valve can not be used for relief valve applications. Please use pressure control valve.
