The Hydraforce EP12-S35 (5283053) is a high-performance, screw-in, cartridge-style, pilot-to-close hydraulic directional element, designed for advanced fluid control in hydraulic systems. This valve operates as a spring-biased blocking valve that shifts to allow full flow from port 1 to port 2 only when the pressure at port 1 exceeds the cumulative pressure of port 3 plus the bias spring pressure. It is tailored for multiple applications with its capability to handle a maximum pressure rating of 345 bar (5000 psi) and a variety of temperature conditions ranging from -40 to +100°C with standard Buna N seals, extending up to +204°C with optional fluorocarbon or high durometer fluorocarbon seals. The EP12-S35 features an industry-common cavity (VC12S3), ensuring compatibility with standard fittings and simplifying installation processes. The manual override option is available with an 80 psi spring, providing additional operational flexibility. The valve also boasts low internal leakage, rated at a maximum of 131 ml/min at its highest pressure threshold, ensuring efficient and reliable performance. With fluid viscosity tolerance ranging from 7.4 to 420 cSt and maximum operating contamination levels specified at ISO 4406:20/18/14, this valve maintains robust performance even in demanding environments. Additionally, the EP12-S35 supports a wide range of hydraulic fluids including mineral-based or synthetic types with lubricating properties. Its versatile design and operational parameters make it suitable for various hydraulic applications requiring precise control over fluid flow and direction.
