The Hydraforce EV20-S34-0-N-20 (5287210) is a screw-in, cartridge-style hydraulic directional element designed for versatile fluid control in hydraulic systems. This model functions as a spring-biased blocking valve that shifts to allow full flow from port 1 to port 2 when port 3 is vented, creating a pressure drop across the internal orifice which exceeds the bias spring pressure. It ensures smooth shift transitions and features a low-pressure drop, enhancing system efficiency. The EV20-S34-0-N-20 is rated for pressures up to 345 bar (5000 psi), with polyurethane seals recommended for maximum pressure operation. It exhibits maximum internal leakage of 197 ml/min at 5000 psi, ensuring reliable performance under high-pressure conditions. The operating fluid temperature range is broad, from -40 to +204°C (-40 to +400°F), making it suitable for diverse operating environments. Weighing approximately 0.82 kg (1.8 lb), this valve fits within industry-common cavity VC20S3 and requires a cartridge installation torque between 88 to 102 Nm (65 to 75 ft-lb). For maintenance and customization, seal kits such as SK20S3NMM (Buna N), SK20S3VMM (Viton), and SK20S3PMM (Polyurethane) are available, along with comprehensive seal kit installation instructions. This model's adaptability and robust specifications make it ideal for various applications requiring precise control of hydraulic flow with minimal energy loss.
