VALVE - CHECK 5 PSI (Crown CR117380-1)

CR117380-1: A damaged check valve can allow reverse flow, leading to system pressure loss and erratic operation. This aftermarket replacement part references Crown as the OE maker and cross-references part number CR117380-1. The valve type is a check valve, which permits flow in one direction only. Its plain mechanical function is to open when forward pressure exceeds a set threshold and close to block backflow. A concrete generic failure consequence is that a stuck-open check valve may cause uncontrolled fluid movement, reducing system responsiveness. During a pressure test, a leaking check valve can prevent the system from holding pressure. Verify the serial number or application, then call (562) 693-7748.
