The Hydraforce 5600143 (RV0820X) is a precision-engineered hydraulic relief valve, designed for low flow circuits that demand minimal 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 displace the spring-opposed poppet from its seat. The RV0820X offers a range of pressure adjustment options, including non-adjustable factory presets and adjustable settings with positive stops to prevent spring compression issues. It features optional spring ranges up to 248 bar (3600 psi) and can respond rapidly to changes in pressure. For applications requiring bidirectional pressure capabilities, an optional bidirectional pressure seal is available. The compact design of the RV0820X makes it suitable for systems where space is at a premium. It has been crafted with features that ensure adjustments cannot be inadvertently altered, enhancing system reliability and safety. The RV0820X also stands out for its robust performance in blocking unwanted flow until required pressure thresholds are met, making it an essential component for efficient hydraulic system management. For those considering upgrades or replacements, the RVD5820 model offers comparable or enhanced features such as better pressure rise characteristics and a smaller size, while maintaining competitive cost and compatibility with existing systems through the VC082B cavity variation. This makes the RVD5820 a strong candidate for both existing and new applications seeking advanced hydraulic relief solutions.
