HydraForce Flow Control SP08-20 Poppet-Type, 2-Way, Normally Closed

HydraForce SP08-20 solenoid-operated, 2-way, normally closed, proportional, poppet-type, screw-in hydraulic cartridge valve for blocking or load-holding applications.

When de-energized, the SP08-20 acts as a check valve, allowing flow from 1 to 2, while blocking flow from 2 to 1. When energised, the cartridge’s poppet lifts to open the 2 to 1 flow path. Flow is proportional to current applied to the coil. Flow varies with manual override.

Features:

• Continuous-duty rated coil
• Efficient wet-armature construction
• Manual override options
• Optional waterproof E-Coils rated up to IP69K
• Industry common cavity
• Compact size
