VALVE DOUBLE PILOT CHECK (JLG JL4640150)

A worn double pilot check valve can cause load drift or uncontrolled movement in a circuit. This aftermarket replacement part references the JLG catalog number JL4640150. The valve type uses two pilot-operated check elements to block flow in both directions until pilot pressure is applied. A common failure consequence is that a leaking check valve allows the load to settle unexpectedly. During a pressure test, a technician may find the valve unable to hold position. Verify the serial number or application, then call (562) 693-7748. The part is a valve double pilot check, a generic component for flow control.
