The Hydraforce SF20-22M-0-N-24ER (5073039) is a solenoid-operated, 2-way, normally closed, poppet-type hydraulic cartridge valve. It is specifically designed for applications requiring load holding or blocking with minimal internal leakage under high pressure. In its de-energized state, the SF20-22 functions as a check valve, allowing flow from port 1 to port 2 while preventing reverse flow. When energized, the poppet lifts to enable bidirectional flow between port 1 and port 2. This valve features a continuous-duty rated coil and a hardened seat for enhanced durability and reduced leakage. It offers optional coil voltages and terminations, interchangeable voltage cartridges, and a unitized molded coil design. The valve is compatible with optional waterproof E-Coils rated up to IP69K and includes corrosion-resistant plating for increased longevity. The SF20-22M-0-N-24ER boasts impressive specifications including a pressure rating of 1.4 to 345 bar (20 to 5000 psi) and a maximum flow rating of 303 lpm (80 gpm). It maintains low internal leakage at a maximum of 10 drops/min at 345 bar (5000 psi). The valve operates effectively across various temperature ranges depending on the seal material: -40 to 100 \u00b0C with buna N seals, -26 to 204 \u00b0C with viton seals, and -54 to 107 \u00b0C with polyurethane seals. This cartridge valve fits into VC20-2 cavities with an installation torque range of 88.4 to 102 N-m (65 to 75 ft-lb), while the coil nut requires a torque of 5.4 to 6.8 N-m (4 to 5 ft-lb). The SF20-22M-0-N-24ER supports mineral-based or synthetic hydraulic fluids within a viscosity range of 7.4 to 420 cSt and adheres to ISO cleanliness code levels of up to 20/18/14 for optimal performance in hydraulic systems.
