The Hydraforce SF20-22-20TD-N-12DL (5073082) is a solenoid-operated, 2-way, normally closed, poppet-type screw-in hydraulic cartridge valve. This model is specifically designed to serve as a load holding or blocking valve in high-pressure applications where low internal leakage is critical. When de-energized, it functions as a check valve, permitting flow from port 1 to port 2 and blocking reverse flow. Upon energization, the poppet lifts to open the flow path from port 2 to port 1 while still allowing flow from port 1 to port 2. The valve features a continuous-duty rated coil and a hardened seat for durability and minimal leakage. It offers optional coil voltages and terminations with interchangeable cartridges and comes with an optional waterproof E-Coil rated up to IP69K for enhanced protection against environmental factors. The corrosion-resistant plating ensures longevity in various conditions. The SF20-22 can handle pressure ratings from 1.4 to 345 bar (20 to 5000 psi) and supports a flow rating of up to 303 lpm (80 gpm). Its maximum internal leakage is limited to 10 drops per minute at maximum pressure. The operating fluid temperature ranges 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. Installation specifications include a VC20-2 cavity type with a cartridge installation torque of between 88.4 and 102 N-m (65 to 75 ft-lb). The valve is compatible with mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. Additional accessories include seal kits like SK20-2X-T and compatible housings for installation flexibility, ensuring the SF20-22 fits seamlessly into various hydraulic systems requiring reliable load-holding capabilities under high-pressure conditions.
