Direct-operated solenoid valve SF08-20

3-waynormally closedhydraulic

A solenoid-operated, 2 way, normally closed, piloted poppet-type, screw-in hydraulic cartridge valve and intended to act as a blocking or load-holding device for low flow circuits. Operation When de-energized, the sf08-20x acts as a check valve, allowing flow from port 1 to port 2, while blocking flow from port 2 to port 1. When energized, the cartridge's poppet lifts to open the port 2 to port 1 flow path. In this mode, flow from port 1 to port 2 is severely restricted. Features Continuous-duty rated coil. Hardened seat for long life and low leakage. Optional coil voltages and terminations. Cartridges are voltage interchangeable. Unitized, molded coil design. Optional waterproof E-Coils rated up to IP69K. Corrosion-resistant plating to 960 hr. salt spray per ASTM B117. Industry common cavity. Compact size. Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties. Fluid Viscosity Range: 7.4 to 420 cSt Maximum Operating Contamination Level: 18/16/13 PER ISO 4406 Environmental Corrosion Protection: 960 hr salt spray per ASTM B117 Cartridge Weight: 0.1 kg (0.22 lb) Internal Wetted Surface Area: 80 cm² (12.47 in²) Cavity: VC08-2 08-size-3-way Cavities Cartridge Installation Torque: 25.8 to 28.5 N-m (19 to 21 ft-lb Maximum Allowable Torque: 54.2 N-m (40 ft-lb) Coil Nut Torque: 5.4 to 6.8 N-m (4 to 5 ft-lb) Orientation Restriction: None
