The Hydraforce 5604000.M276 (5604000.M276) is a screw-in, cartridge style, direct acting, poppet type hydraulic thermal relief valve designed to prevent cylinder damage caused by temperature-induced pressure intensification. This specific valve, identified as the TR04-B20, is not intended for use as a general relief valve nor for protection against load-induced pressure spikes. In operation, the TR04-B20 effectively blocks flow from port 1 to port 2 until the pressure at port 1 reaches a level sufficient to displace the spring-opposed poppet from its seat. It is crucial that the pressure at port 2 does not exceed 500 psi (34.5 bar) above that of port 1, as any excess pressure at port 2 will add to the overall pressure setting. This valve is specifically engineered for applications where thermal expansion may cause detrimental increases in hydraulic system pressure, thereby providing a safeguard against potential equipment damage due to such conditions.
