The Hydraforce SF20-22-20TD-N-12EG (5073111) is a solenoid-operated, 2-way, normally closed, poppet-type screw-in hydraulic cartridge valve. This versatile valve is engineered to function as a load holding or blocking valve in high-pressure applications that demand low internal leakage. When de-energized, it acts as a check valve, allowing flow from port 1 to port 2 while blocking reverse flow. Energizing the valve lifts the poppet to open the flow path from port 2 to port 1 and also permits flow from port 1 to port 2. It features a continuous-duty rated coil and a hardened seat for enhanced longevity and minimal leakage. The unit offers interchangeable cartridges with optional coil voltages and terminations, including waterproof E-Coils rated up to IP69K for added durability against harsh environments. It boasts corrosion-resistant plating and fits industry-standard cavities. The SF20-22-20TD-N-12EG supports pressure ratings from 1.4 to 345 bar (20 to 5000 psi) and can handle a maximum flow rate of up to 303 lpm (80 gpm). Its internal leakage is limited to a maximum of 10 drops per minute at 345 bar (5000 psi). Designed for various temperature ranges based on seal type, it operates with mineral-based or synthetic hydraulic fluids within a viscosity range of 7.4 to 420 cSt, adhering to ISO cleanliness standards of up to 20/18/14 per ISO 4406. The cartridge installation torque ranges between 88.4 and 102 N-m (65 to 75 ft-lb), with no orientation restrictions needed during installation. Accessories like seal kits are available for maintenance purposes, ensuring extended operational life in demanding applications requiring reliable performance under pressure variations.
