Description
HydraForce SP12-20 solenoid-operated, 2-way, normally closed, proportional, poppet-type, screw-in hydraulic cartridge valve for blocking or load-holding applications.
When de-energised, the SP12-20 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 option
- Optional waterproof E-Coils rated up to IP69K
- Industry common cavity
- Metering option
