The Hydraforce SF20-23-0-N-00 (5074000) is a solenoid-operated, 2-way, normally open, poppet-type hydraulic cartridge valve. It is engineered to serve as a load-holding or blocking valve, particularly in applications demanding low internal leakage at high pressure. In its de-energized state, the poppet lifts to allow flow from port 2 to port 1 and also permits flow in the reverse direction. When energized, it functions as a check valve, restricting flow from port 2 to port 1 while allowing reverse flow. This valve boasts features such as a continuous-duty rated coil and a hardened seat for durability and minimal leakage. It offers optional coil voltages and terminations with voltage interchangeability among cartridges. The unitized molded coil design includes optional waterproof E-Coils rated up to IP69K for enhanced protection against harsh environments. The SF20-23 model can handle pressures ranging from 1.4 to 345 bar (20 to 5000 psi) and supports a maximum flow rate of up to 303 liters per minute (80 gallons per minute). Its internal leakage is limited to a maximum of 10 drops per minute at full pressure. The valve operates efficiently across various fluid temperatures depending on the seal type used: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals. It accommodates mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. Installation requires fitting into VC20-2 cavities with specified torque parameters: cartridge installation torque ranges from 88.4 to 102 N-m, and maximum allowable torque is set at 169.4 N-m. The unit weighs approximately 1.48 lb (0.67 kg) and has an internal wetted surface area of about 397 cm\u00b2 (61.6 in\u00b2). Optional accessories include seal kits and housings suitable for various configurations.
