The Hydraforce 5601710.28 (5601710.28) is a screw-in, cartridge-style, direct-acting, bi-directional poppet type hydraulic relief valve. This component serves as a pressure-limiting device in demanding hydraulic circuits that require low hysteresis and minimal internal leakage. It effectively blocks flow between port 1 and port 2 in either direction while keeping the spring chamber drained at port 3. The valve activates when a pre-set pressure is reached at either port, causing the spring-opposed poppet to unseat and relieve pressure. Notable features include adjustments that cannot be backed out of the valve, preventing springs from becoming solid, and the use of hardened parts for enhanced durability. Its compact size aligns with industry standards, making it a versatile choice for various hydraulic applications.
