Direct-operated solenoid valve SF08-21

2-waynormally openhydraulic

SOLENOID CARTRIDGE VALVE POPPET, 2 WAY, NORMALLY OPEN HIGH PRESSURE A solenoid-operated, 2 way, piloted, poppet-type, normally open, screw in hydraulic cartridge valve designed for low leakage in higher pressure load-holding applications. Operation When de-energized, the sf08-21xx allows flow from port 2 to port 1. Flow from port 1 to port 2 is severely restricted in this mode. When energized, the valves poppet closes on its seat, blocking flow from port 2 to port 1. In this mode the cartridge will allow port 1 to port 2 flow after overcoming the solenoid force (requires 50 to 150 psi [3,4 to 10,3 bar]). Features Continuous-duty rated coil. Corrosion-resistant plating. Hardened seat for long life and low leakage. Optional coil voltages and terminations. Cartridges are voltage interchangeable. Unitized, molded coil design. Manual override option. Optional waterproof E-Coils rated up to IP69K. Industry common, compact size.
