The Hydraforce 5600303.21 (5600303.21) is a hydraulic relief valve, specifically designed for lower flow circuits requiring minimal internal leakage. This screw-in, cartridge-style, direct-acting poppet valve efficiently blocks 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 various pressure adjustment options, including non-adjustable factory presets and adjustments labeled A, B, and C with positive stops that prevent springs from solidifying. The valve supports optional spring ranges up to 248 bar (3600 psi) and offers rapid response to pressure changes. Additionally, it provides an optional bi-directional pressure feature with the necessary bi-directional pressure seal option. The compact size of this valve makes it suitable for applications with space constraints. While this model serves existing and new applications effectively, the RVD58-20 is noted as a best-in-class alternative that can replace this valve in most scenarios due to its comparable pressure and flow ratings, similar response rate, better pressure rise characteristics, smaller size, and competitive cost. However, it requires a VC08-2B cavity variation for installation. Some manifolds may allow for drop-in replacement of this model with assistance available for application evaluation if needed.
