The Hydraforce 5600409.M91 (Material Number: 5600409.M91) is a screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve designed for lower flow circuits that demand low internal leakage. It operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to overcome the spring-opposed poppet. This model features various pressure adjustment options, including non-adjustable factory presets, and adjustments that cannot be backed out of the valve. Options A, B, and C include 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 capability with a specific seal option required for this feature. Its compact size makes it suitable for applications with space constraints. While it can be used in existing and new applications, Hydraforce suggests considering the RVD58-20 as a best-in-class alternative with comparable pressure and flow ratings, better pressure rise characteristics, smaller size, and no dynamic seal requirement. Note that a VC08-2B cavity variation is necessary for installation in some manifolds; however, certain manifolds may allow for drop-in replacement without modification.
