VALVE CHECK (Crown CR117380-4)

A worn check valve can allow reverse flow, leading to system pressure loss and reduced performance. This aftermarket replacement part references Crown as the OE maker and carries the cross-reference number CR117380-4. The valve check is a type of valve that permits fluid or gas to flow in one direction only. Its plain mechanical function is to block backflow when the pressure differential reverses. A common generic failure consequence is that a stuck-open check valve may cause erratic operation or failure to hold load. Keeping the check valve in sound condition helps maintain directional control in the circuit. Verify the serial number or application, then call (562) 693-7748.
