The Hydraforce EP10-S38-0-N-80 (5282300) is a screw-in, cartridge-style hydraulic directional element designed for versatile functionality in controlling fluid flow in hydraulic systems. This spring-biased poppet valve operates by blocking or allowing flow between ports based on differential pressure and spring force. It effectively blocks flow from port 1 to port 2 or vice versa until the pressure at either of these ports surpasses the combined pressure at port 3 and the bias spring’s force. Under conditions where there is no pressure at port 3, the flow is permitted once the bias spring force is exceeded by the pressure at either port 1 or port 2. This model boasts a balanced area ratio of 1:1 between ports 1 and 2, and a ratio of 1:2 from these ports to port 3 when in a closed state, ensuring efficient operation. The EP10-S38-0-N-80 supports a maximum operating pressure of up to 345 bar (5000 psi) and accommodates various fluid temperatures ranging from -40°C to +100°C with Buna N seals, and broader ranges with other seal types, making it suitable for diverse operating environments. Additionally, its design features include low internal leakage (maximum of 0.2 ml/min at 241 bar), compatibility with mineral-based or synthetic hydraulic fluids, and a broad fluid viscosity range (7.4 to 420 cSt). The unit's corrosion protection withstands up to 960 hours of salt spray per ASTM B117 standards, highlighting its durability in harsh conditions. For installation, this valve uses a VC10S3 cavity and requires no specific orientation, offering flexibility in system design. It also supports various accessory options such as different seal kits for maintenance and compatible housings for enhanced utility. This model is ideal for applications requiring reliable directional control of hydraulic fluids under varying pressures and temperatures.
