The Hydraforce EP20-S38-0-N-80 (5287708) is a screw-in cartridge-style hydraulic directional element, specifically designed as a spring-biased bidirectional blocking poppet type valve. This model excels in controlling fluid flow direction under varying pressure conditions. The valve effectively blocks flow from port 1 to 2 or vice versa until the pressure at either of these ports surpasses the combined pressure at port 3 along with the bias spring force. In scenarios where there is no pressure at port 3, the valve allows flow from port 1 to 2 or in reverse once the bias spring force is exceeded. This component features equal area ratios between ports 1 and 2 (1:1), and an area ratio of 1:2 between ports 1 or 2 and port 3, optimizing its efficiency in various hydraulic applications. It supports multiple functions due to its versatile design and exhibits a low-pressure drop, enhancing overall system performance. The common industry cavity design (VC20S3) ensures compatibility with standard hydraulic systems. Constructed from steel with hardened work surfaces and zinc-plated exposed surfaces, this valve is built for durability and resistance against wear in harsh environments. Its operational fluid temperature ranges from -40 to +120 degrees Celsius (-40 to +248 degrees Fahrenheit), accommodating a broad spectrum of working conditions. The EP20-S38-0-N-80 can handle pressures up to 241 bar (3500 psi) with maximum internal leakage maintained at a minimal rate of about 0.6 ml/min at this maximum pressure level. Additional accessories like various seal kits are available including Buna N, Viton, and Polyurethane options, each tailored for specific environmental requirements and ensuring extended service life and reliability of the seal elements within diverse operational contexts.
