VALVE-CHECK 3 PSI (JLG JL94757)

A check valve that opens at 3 PSI can fail to reseat properly, allowing reverse flow and loss of system pressure. The JLG catalog reference for this aftermarket replacement part is JL94757. Its plain mechanical function is to permit flow in one direction while blocking flow in the opposite direction. A stuck-open valve may cause uncontrolled fluid movement and reduced operational control. Verify the serial number or application, then call (562) 693-7748. This part is a valve type commonly used in fluid circuits to maintain directional flow. A failed check valve can lead to sluggish or unresponsive system behavior.
