The Hydraforce 5600409.21.47 (Material Number: 5600409.21.47) is a screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve designed for lower flow circuits where low internal leakage is crucial. This valve effectively blocks flow from port 1 to port 2 until the pressure at port 1 surpasses a set threshold, prompting the spring-opposed poppet to unseat and allow flow. It offers multiple pressure adjustment options, including non-adjustable factory presets and adjustments labeled A, B, and C, which incorporate positive stops to prevent the springs from becoming solid. The valve supports optional spring ranges up to 248 bar (3600 psi), ensuring rapid response to pressure changes. Additionally, it features an optional bi-directional pressure seal for applications requiring such functionality. Its compact size makes it suitable for installations where space is limited. The RV08-20X model has been superseded by the RVD58-20 model in new applications due to improvements in performance metrics such as better pressure rise characteristics and a smaller form factor while maintaining comparable pressure and flow ratings as well as response rates. However, the RV08-20X remains a viable option for existing systems or where specific application conditions necessitate its use. It requires a VC08-2B cavity variation for installation, although some manifolds may allow for drop-in replacement without significant modifications.
