The Hydraforce SF20-22-0-N-115AG (5073018) is a solenoid-operated, 2-way, normally closed, poppet-type hydraulic cartridge valve. It is engineered to serve as a load-holding or blocking valve in applications that demand minimal 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 poppet lifts to enable flow from port 2 to port 1 and allows bi-directional flow between ports. This versatile component features a continuous-duty rated coil and a hardened seat for durability and reduced leakage. It offers optional coil voltages and terminations, with interchangeable cartridges for varying voltage requirements. The unitized, molded coil design includes optional waterproof E-Coils rated up to IP69K for enhanced protection against harsh environments. The valve is capable of handling pressures ranging from 1.4 to 345 bar (20 to 5000 psi) and supports a maximum flow rate of 303 lpm (80 gpm). Maximum internal leakage is limited to 10 drops per minute at full pressure capacity (345 bar). 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. Suitable for use with mineral-based or synthetic hydraulic fluids possessing lubricating properties, it accommodates a fluid viscosity range of 7.4 to 420 cSt. Installation specifications include compatibility with VC20-2 cavities and require cartridge installation torque between 88.4 to 102 N-m (65 to 75 ft-lb). The product weighs approximately 1.43 lb (0.65 kg) and has an internal wetted surface area of about 378 cm\u00b2 (58.6 in\u00b2). Accessories such as seal kits and housings are available for additional customization options.
