VALVE - RELIEF (Hyster HY0319631)

A relief valve that fails to open at its set pressure can allow system pressure to climb until a component ruptures. Hyster originally cataloged this valve under part number HY0319631. The valve's plain mechanical function is to open at a predetermined pressure and divert flow to protect downstream parts. A common generic failure consequence is that a stuck-closed relief valve causes pressure spikes that damage seals or burst lines. Keeping a relief valve in sound condition helps prevent sudden pressure-related failures during operation. This aftermarket replacement part references the Hyster catalog number HY0319631. Verify the serial number or application, then call (562) 693-7748.
