The Hydraforce SF20-23-0-N-24ER/Z (5074031N) is a solenoid-operated, 2-way, normally open, poppet-type hydraulic cartridge valve. This versatile component is specifically designed to function as a load-holding or blocking valve in systems that require minimal internal leakage at high pressures. When de-energized, the poppet opens to allow flow from port 2 to port 1 and also permits flow in the reverse direction. Upon energization, it acts as a check valve by blocking flow from port 2 to port 1 while allowing reverse flow. The valve features a continuous-duty rated coil, a hardened seat for longevity and reduced leakage, and corrosion-resistant plating for durability. It offers optional coil voltages and terminations with voltage interchangeability among cartridges. The unitized, molded coil design includes optional waterproof E-Coils rated up to IP69K for enhanced protection. The SF20-23 model can handle pressure ratings from 1.4 to 345 bar (20 to 5000 psi) and supports flow rates up to 303 lpm (80 gpm). Its maximum internal leakage is limited to just ten drops per minute at the highest pressure rating of 345 bar (5000 psi). It operates effectively across various temperature ranges depending on the seal type used; from -40\u00b0C to 100\u00b0C with Buna N seals, -26\u00b0C to 204\u00b0C with fluorocarbon seals, and -54\u00b0C to 107\u00b0C with polyurethane seals. Designed for installation in VC20-2 cavities, this cartridge requires an installation torque of between 88.4 and 102 N-m (65 to 75 ft-lb), with a maximum allowable torque of up to 169.4 N-m (125 ft-lb). The coil nut should be torqued between 5.4 and 6.8 N-m (4 to 5 ft-lb). This product supports mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and adheres to ISO cleanliness standards of up to level 20/18/14 per ISO4406 for optimal performance.
