The Hydraforce 5613972 (5613972) is a screw-in, cartridge-style, direct-acting, differential area, poppet-type bidirectional hydraulic relief valve. This component is designed to efficiently manage hydraulic pressure by allowing flow between ports when the pressure at either port exceeds the nominal setting value. A notable feature of this valve is its sensitivity to back pressure; any back pressure at one port will directly affect the nominal setting of the opposite port on a 1:1 basis. This ensures precise control in various hydraulic applications. The CR10-28 model incorporates adjustments that cannot be backed out of the valve, preventing springs from going solid and ensuring reliable performance over time. Built with a hardened spool and cage, it offers enhanced durability and longevity. Its industry-common size makes it a versatile choice for integration into existing systems without requiring extensive modifications. This hydraulic relief valve is particularly suitable for applications requiring dependable pressure control and protection against overpressure conditions in bidirectional flow scenarios.
