The Hydraforce 5624044 (5624044) is a screw-in, cartridge-style, pilot-operated spool-type relief valve designed for use as a pressure-limiting device in demanding hydraulic circuits. This two-stage valve is engineered for applications requiring fast response and low hysteresis. It operates by blocking flow from port 1 to port 2 until the pressure at port 1 reaches a level sufficient to unseat the pilot relief, which then allows the main stage to shift and opens port 1 to port 2. Notably, this valve cannot be used in cross-over relief applications. The RV52-26X features adjustments that cannot be backed out of the valve, with adjustment options A, B, and C incorporating positive stops to prevent the springs from becoming solid. It is constructed with a hardened spool and cage to ensure long life and provides rapid, smooth responses to pressure surges. Additionally, it offers a cost-effective cavity design.
