The Hydraforce SF20-22-0-N-00 (5073000) is a solenoid-operated, 2-way, normally closed, poppet-type hydraulic cartridge valve. This valve is specifically designed to function as a load holding or blocking valve in applications that require minimal internal leakage at high pressure. When de-energized, the SF20-22 acts as a check valve, allowing flow from port 1 to port 2 while blocking reverse flow. Upon energization, the poppet lifts to open the flow path from port 2 to port 1 and also allows flow from port 1 to port 2. Key features include a continuous-duty rated coil, hardened seat for durability and low leakage, optional coil voltages and terminations, and interchangeable voltage cartridges. The unitized molded coil design offers additional protection with optional waterproof E-Coils rated up to IP69K and corrosion-resistant plating. The valve fits industry-standard cavities and supports pressures ranging from 1.4 to 345 bar (20 to 5000 psi) with a maximum flow rating of 303 lpm (80 gpm). It maintains minimal internal leakage of up to 10 drops per minute at maximum pressure. Operating fluid temperatures vary based on seal type: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with Viton seals, and -54 to 107 \u00b0C with polyurethane seals. The valve can handle fluids within a viscosity range of 7.4 to 420 cSt and is compatible with mineral-based or synthetic hydraulic fluids with lubricating properties. Installation requires cavity VC20-2 and specific torque settings for both cartridge installation (88.4 to 102 N-m) and coil nut torque (5.4 to 6.8 N-m). Seal kits are available under SK20-2X-T for maintenance needs.
