The Hydraforce 5911210 (5911210) is a screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve designed for lower flow circuits that require minimal internal leakage. This valve operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to move the spring-opposed poppet off its seat. It features adjustments that cannot be backed out and offers various pressure adjustment options, including non-adjustable factory presets. The adjustment options\u2014A, B, and C\u2014are equipped with positive stops to prevent springs from going solid. The valve supports optional spring ranges up to 248 bar (3600 psi) and provides rapid response to pressure changes. Additionally, it offers an optional bi-directional pressure feature that requires a specific bi-directional pressure seal option. Its compact size makes it versatile for various applications. This product has been superseded by the RVD58-20 model, which is recommended for new applications due to its superior performance characteristics such as comparable pressure and flow ratings, enhanced response rate, better pressure rise characteristics, smaller size, and competitive cost. However, the Hydraforce 5911210 remains a viable option for existing applications where these specific features are required or preferred. It requires a VC08-2B cavity variation for installation, though some manifolds may allow it as a drop-in replacement.
