The Hydraforce SV16-21K-0-N-12ER (5069172) is a solenoid-operated, 2-way, normally open, poppet-type hydraulic cartridge valve. This screw-in valve is specifically designed for load-holding or blocking applications where low internal leakage is essential. When the valve is de-energized, the poppet opens the flow path from port 2 to port 1 while restricting flow from port 1 to port 2. Upon energization, the flow path from port 2 to port 1 closes, allowing it to function as a check valve that permits flow from port 1 to port 2 after overcoming the solenoid force of 50 to 100 psi (3.4 to 6.9 bar). The SV16-21 features a continuous-duty rated coil and a hardened seat for enhanced durability and minimal leakage. It offers optional coil voltages and terminations with efficient wet-armature construction and voltage-interchangeable cartridges. The unitized, molded coil design includes a manual override option and waterproof E-Coils rated up to IP69K. The pressure ratings include a working pressure of up to 207 bar (3000 psi), static pressure rating of up to 250 bar (3650 psi) based on one million cycles, proof pressure of up to 345 bar (5000 psi), and burst pressure reaching up to 965 bar (14000 psi). Maximum internal leakage is limited to three drops per minute at full operating pressure. It operates effectively in fluid temperatures ranging from -40\u00b0C (-40\u00b0F) with Buna N seals or -26\u00b0C (-15\u00b0F) with Viton seals, up to respective maximums of +100\u00b0C (+212\u00b0F) or +204\u00b0C (+400\u00b0F). Compatible with mineral-based or synthetic hydraulic fluids with lubricating properties, it accommodates fluid viscosities between 7.4 and 420 cSt. Installation requires VC16-2 cavities with cartridge installation torque specifications ranging from 62.4 N-m (46 ft-lb) to 73.2 N-m (54 ft-lb), ensuring reliable performance in demanding environments without orientation restrictions.
