Refer to back page 0 for Safety Instructions and pages to for Flow Control Equipment Precautions. Design/Selection Caution 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 is the when the valve begins to open, and not the when the valve is fully open.. The check valve has a construction, in which it is closed by the differential generated when the inlet (IN side) or outlet (OUT side) solenoid valve is switched. Be aware that the check valve does not close completely and the outlet (OUT side) may drop when the inlet (IN side) drops gently and the differential becomes smaller than the minimum operating or cracking. 78

Refer to back page 0 for Safety Instructions and pages to for Flow Control Equipment Precautions. A certain amount of leakage is allowed in the specifications of this product. Please note that it is not suitable for holding over an extended period of time. Design/Selection Caution 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 cracking is the when the valve begins to open, and not the when the valve is fully open.. The check valve has a construction, in which it is closed by the differential generated when the inlet (IN side) or outlet (OUT side) solenoid valve is switched. Be aware that the check valve does not close completely and the outlet (OUT side) may drop when the inlet (IN side) drops gently and the differential becomes smaller than the minimum operating or cracking. 789
