The Hydraforce SF20-22-20TD-N-12EY (5073109) is a solenoid-operated, 2-way, normally closed, poppet-type hydraulic cartridge valve. It is designed to serve as a load holding or blocking valve in applications that demand low internal leakage at high pressure. In its de-energized state, the SF20-22 functions as a check valve, permitting flow from port 1 to port 2 while preventing reverse flow. When energized, the valve allows bidirectional flow between ports 1 and 2 by lifting the poppet to open the pathway from port 2 to port 1. The valve features a continuous-duty rated coil and boasts a hardened seat for enhanced durability and minimized leakage. Users can choose from various coil voltages and terminations, with cartridges being voltage interchangeable. The unitized molded coil design includes optional waterproof E-Coils rated up to IP69K for added protection against environmental factors. Furthermore, it is coated with corrosion-resistant plating and fits industry-standard cavities. This hydraulic cartridge valve has impressive performance specifications including a pressure rating of up to 345 bar (5000 psi) and a maximum flow rate of 303 liters per minute (80 gallons per minute). It maintains minimal internal leakage at just 10 drops per minute under maximum pressure conditions. The operating fluid temperature ranges vary based on seal type: -40\u00b0C to 100\u00b0C with Buna N seals, -26\u00b0C to 204\u00b0C with Viton seals, and -54\u00b0C to 107\u00b0C with polyurethane seals. It supports fluids such as mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. Installation requires specific torque settings: cartridge installation torque between 88.4 and 102 N-m (65 to 75 ft-lb), and coil nut torque between 5.4 and 6.8 N-m (4 to 5 ft-lb). The SF20-22 is compatible with VC20-2 cavities and comes with optional accessories like seal kits and housings for versatile application needs.
