The Hydraforce 5601760.M138 (5601760.M138) is a high-performance hydraulic relief valve designed for pressure limiting in common hydraulic circuit protection. This screw-in, cartridge-style valve features a direct-acting, differential area poppet type that is internally vented and bidirectional. It effectively blocks flow from either port 1 or port 2 and activates when a predetermined pressure is reached at either port, causing the spring-opposed poppet to unseat. The CR08-28X model ensures rapid response to load changes with minimal hysteresis, low pressure rise, and reduced internal leakage, making it suitable for dynamic hydraulic systems. It offers adjustable pressure settings ranging from 138 to 276 bar (2000 to 4000 psi) and boasts enhanced durability with corrosion protection rated at 960 hours of salt spray per ASTM B117 standards. Built with hardened parts for extended life, this valve fits into an industry-common cavity design, ensuring compatibility and ease of integration into various systems.
