PRESSURE RELIEF VALVE (Hyster HY1584220)

A pressure relief valve that does not open at the correct set point can allow system pressure to exceed safe limits. This aftermarket replacement part references Hyster catalog number HY1584220. The valve's general function is to release pressure once a predetermined threshold is reached. A plain mechanical function is that the valve uses a spring-loaded mechanism to hold a seal closed until the set pressure is overcome. A concrete generic failure consequence is that a stuck-closed valve can cause pressure buildup, leading to component rupture or seal failure. Verify the serial number or application, then call (562) 693-7748. This part is listed as a pressure relief valve in the valve category.
