The Hydraforce SV10-21-8T-N-12DL (5021612) is a solenoid-operated, 2-way, piloted, poppet-type hydraulic cartridge valve designed primarily for low leakage in load-holding applications. This normally open valve allows fluid flow from port 2 to port 1 when de-energized, with severely restricted flow in the opposite direction. Upon energization, the poppet closes against its seat to block flow from port 2 to port 1 while allowing controlled flow from port 1 to port 2 once a specific solenoid force of 50 to 150 psi (3.4 to 10.3 bar) is overcome. Key features include a continuous-duty rated coil and a hardened seat that ensures longevity and minimal leakage. The valve offers optional coil voltages and terminations along with efficient wet-armature construction. Its cartridges are voltage interchangeable and feature a unitized, molded coil design. Additional options include manual overrides and IP69K-rated waterproof E-Coils for enhanced durability under harsh conditions. The SV10-21-8T-N-12DL can operate within a fluid temperature range of -40°C to +100°C with Buna N seals or up to +204°C with fluorocarbon seals, making it versatile for various thermal environments. The valve supports mineral-based or synthetic hydraulic fluids with viscosities ranging from 7.4 to 420 cSt and tolerates a maximum operating contamination level as specified by ISO 4406. This valve's robust design accommodates pressures up to 207 bar (3000 psi), proof pressures up to 344 bar (5000 psi), and burst pressures up to 779 bar (11300 psi). It also exhibits maximum internal leakage of merely three drops per minute at full pressure, ensuring efficient performance in critical applications.
