The Hydraforce SF20-22M-0-P-00 (5073002P) is a solenoid-operated, 2-way, normally closed, poppet-type hydraulic cartridge valve. This screw-in valve is expertly designed to function as a load-holding or blocking valve in applications that require low internal leakage even at high pressures. When in its de-energized state, the SF20-22 operates as a check valve, allowing flow from port 1 to port 2 while preventing reverse flow. Upon energization, the poppet lifts to enable flow from port 2 to port 1 and permits bi-directional flow between ports. This model features a continuous-duty rated coil and a hardened seat for enhanced durability and minimal leakage. It also offers optional coil voltages and terminations, with cartridges that are voltage interchangeable for flexibility in various applications. The unitized molded coil design includes optional waterproof E-Coils rated up to IP69K for robust performance in harsh environments. Additionally, it boasts corrosion-resistant plating and fits industry common cavities. The SF20-22M-0-P-00 has a pressure rating ranging from 1.4 to 345 bar (20 to 5000 psi) and supports a maximum flow of 303 liters per minute (80 gallons per minute). Its maximum internal leakage is limited to just 10 drops per minute at maximum pressure of 345 bar (5000 psi). Temperature ratings 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's fluid compatibility includes mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. It can handle operating contamination levels up to ISO code 20/18/14. Installation specifications include compatibility with VC20-2 cavities requiring an installation torque of between 88.4 and 102 N-m (65 to 75 ft-lb). The coil nut torque ranges from 5.4 to 6.8 N-m (4 to 5 ft-lb), with no orientation restrictions during installation. Accessories available include seal kits (SK20-2X-T) and various coil sizes for enhanced versatility in application setups.
