The Hydraforce SV10-21-0-N-24EY (5021128) is a solenoid-operated, 2-way, piloted, poppet-type hydraulic cartridge valve that is normally open and designed for low leakage in load-holding applications. This valve ensures controlled flow from port 2 to port 1 when de-energized while severely restricting flow in the opposite direction. When energized, the poppet closes on its seat, blocking flow from port 2 to port 1, but allows flow from port 1 to port 2 after overcoming a solenoid force of 50 to 150 psi (3.4 to 10.3 bar). This model features a continuous-duty rated coil and a hardened seat that enhances durability and minimizes leakage. It also offers optional coil voltages and terminations, efficient wet-armature construction, voltage interchangeable cartridges, unitized molded coil design, and a manual override option. Additional options include waterproof E-Coils rated up to IP69K for superior environmental resistance. The SV10-21-0-N-24EY is capable of handling pressure up to 207 bar (3000 psi) with proof pressure at 344 bar (5000 psi) and burst pressure at 779 bar (11300 psi). It supports fluid flow rates up to 102 lpm (27 gpm) based on a pressure of 34.4 bar (500 psi), with maximum internal leakage maintained at minimal levels. The valve operates efficiently within a fluid temperature range of -40°C to +100°C (-40°F to +212°F) using Buna N seals or up to +204°C (+400°F) with fluorocarbon seals. This product is suitable for various hydraulic systems requiring reliable load-holding capabilities along with flexibility in integration due to its industry-standard cavity VC102 specification and compatibility with diverse seal materials ensuring adaptability across different operational environments.
