The Hydraforce 5600400.21.7 (5600400.21.7) is a screw-in, cartridge-style hydraulic relief valve, specifically designed for lower flow circuits that demand low internal leakage. This direct-acting, poppet-type valve operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to move the spring-opposed poppet from its seat. It is engineered to handle higher operating pressures up to 345 bar (5000 psi) and offers a bi-directional pressure option. The valve features a rapid response to pressure changes and comes in a compact size, making it suitable for applications where space is limited. Various adjustment options are available; however, these adjustments cannot be backed out of the valve and are designed to prevent springs from going solid, ensuring reliable performance under specified conditions. While this model serves existing and new applications effectively, it is noted that the RVD58-20 is recommended as a best-in-class alternative with comparable pressure and flow ratings but offering better pressure rise characteristics and a smaller size. The VC08-2B cavity variation is necessary for installation, although some manifolds may allow for drop-in replacement without additional modifications.
