VALVE CHECK (Crown CR117380-2)

CR117380-2: A worn check valve can allow reverse flow, reducing system pressure and causing erratic operation. This aftermarket replacement part references Crown as the OE maker and cross-references part number CR117380-2. 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 pressure drops on the outlet side. A common generic failure consequence is that a stuck-open check valve leads to loss of prime or uncontrolled cycling. Keeping a check valve in sound condition helps maintain consistent directional flow in a closed circuit. Verify the serial number or application, then call (562) 693-7748.
