The Hydraforce 5600407.M138 (5600407.M138) is a screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve designed for lower flow circuits that require minimal internal leakage. This model effectively blocks flow from port 1 to port 2 until sufficient pressure at port 1 forces the spring-opposed poppet off its seat. It features a range of pressure adjustment options, including non-adjustable factory presets and positive stops to prevent springs from going solid. The valve offers optional spring ranges up to 248 bar (3600 psi) and provides rapid response to pressure changes. Additionally, it has an optional bi-directional pressure feature that requires a bi-directional pressure seal option. Its compact size makes it suitable for applications where space is limited. While this model serves existing and new applications well, the RVD58-20 is recommended as a best-in-class alternative due to its comparable pressure and flow ratings, improved response rate, better pressure rise characteristics, smaller size, and competitive cost. The VC08-2B cavity variation is required for this model, and some manifolds may allow for drop-in replacement.
