The Hydraforce SP12-21-0-N-00 (5003985) is a solenoid-operated, 2-port, normally open, poppet-type, proportional, screw-in hydraulic cartridge valve. This valve is specifically designed for low leakage blocking and load-holding applications. It functions as a check valve when energized, allowing fluid flow from port 1 to port 2 while blocking the reverse flow. Conversely, when de-energized, the poppet lifts to permit flow from port 2 to port 1. The SP12-21-0-N-00 features a continuous-duty rated coil and efficient wet-armature construction. It incorporates optional waterproof E-Coils that are rated up to IP69K and fits an industry-common cavity. The valve offers robust performance specifications including a pressure rating of up to 250 bar (3625 psi), proof pressure of 344 bar (5000 psi), and a burst pressure of 779 bar (11300 psi). It supports a maximum flow rate of 102 liters per minute (27 gallons per minute) based on pressure drop performance graphs. The maximum internal leakage is minimal at only five drops per minute at full pressure. Its operational capabilities are supported across various temperature ranges depending on the seal material used—ranging from -40°C to +100°C with Buna N seals up to -26°C to +204°C with fluorocarbon seals. This valve is suitable for use with mineral-based or synthetic hydraulic fluids that have lubricating properties within a viscosity range of 7.4 to 420 cSt and can operate effectively within contamination levels up to ISO 4406:2018/14. The SP12-21-0-N-00’s design ensures durability and reliability in demanding environments, underscored by its corrosion protection that withstands up to 960 hours of salt spray per ASTM B117 standards.
