VALVE CHECK (JLG JL4641156)

JL4641156: A damaged check valve can allow reverse flow in a fluid system, leading to loss of pressure or system failure. The JLG catalog reference for this aftermarket replacement part is JL4641156. This valve type permits flow in one direction only and blocks flow in the opposite direction. A common failure consequence is that a stuck-open check valve may cause backflow, preventing proper system operation. During system testing, a leaking check valve often produces audible chatter or visible fluid bypass. Verify the serial number or application, then call (562) 693-7748. This part is an aftermarket replacement sourced from the JLG catalog.
