The Hydraforce 5612571.M21 (5612571.M21) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for hydraulic circuit protection as a pressure-limiting device. The xrvd50-20x model blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the poppet, providing fast response to load changes with low hysteresis, low pressure rise, and minimal internal leakage. Notable features include non-adjustable valve settings that prevent adjustments from being inadvertently backed out and an adjuster height that remains constant regardless of pressure setting adjustments. Constructed with a hardened poppet and cage, it ensures long-lasting durability. The valve offers optional spring ranges up to 345 bar (5000 psi) and is compatible with industry-common cavities, allowing for rapid response to pressure changes in various hydraulic applications.
