The Hydraforce 5600409U.28 (Material Number: 5600409U.28) is a screw-in, cartridge-style, direct-acting poppet type hydraulic relief valve designed for lower flow circuits that demand low internal leakage. This model effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the spring-opposed poppet. The valve features adjustment options that cannot be backed out, with a variety of pressure adjustment choices including non-adjustable factory presets. Options A, B, and C come with positive stops to prevent the springs from becoming solid. It offers optional spring ranges up to 248 bar (3600 psi) and provides rapid response to pressure changes. Additionally, there is an option for bi-directional pressure with a special seal requirement. Its compact size makes it suitable for applications where space is limited. The valve has been superseded by the RVD58-20 model, which offers comparable pressure and flow ratings along with improved pressure rise characteristics and a smaller size, though some manifolds may allow for drop-in replacement of this older model with assistance available for application evaluation.
