The Hydraforce 5601760 (5601760) is a CR08-28X model, which serves as a screw-in, cartridge-style hydraulic relief valve. This direct-acting, differential area valve is designed to function as a pressure-limiting device, providing essential protection for common hydraulic circuits. Its internally vented, bidirectional poppet type design allows it to effectively block flow from either port 1 or port 2. Once the set pressure is reached at either port, the spring-opposed poppet is displaced from its seat, enabling flow and thus relieving pressure. The valve is engineered for rapid response to load changes while maintaining low hysteresis and minimal internal leakage, making it suitable for applications requiring precise control and reliability. The CR08-28X offers a range of adjustment options with a pressure setting range between 138 to 276 bar (2000 to 4000 psi). It features robust construction with hardened parts that ensure long life and durability under demanding conditions. Additionally, the valve boasts corrosion protection capable of withstanding up to 960 hours in salt spray testing per ASTM B117 standards, ensuring resilience in harsh environments. The design incorporates an industry-common cavity for ease of integration into existing systems or new installations.
