SP08-25 Spool, 2-Way, Normally Open (SP08-25)
A proportional solenoid-operated, two-way, spool-type, normally open, bi-directional, screw-in hydraulic cartridge valve.
Product Operation
When de-energized, the SP08-25 allows flow from 1 to 2 or from 2 to 1. When partially energized, the valve begins to throttle the flow in either direction. When fully energized, flow is blocked in either direction.
External circuitry is required to ramp current.
Note: If low voltage is expected on the machine, 12 or 24 volt systems will require the use of 10 volt or 20 volt coils respectively. See “SP Valves and Coil Operating Parameters,” page 2.002.1.
Product Features
• Industry-common cavity.
• Continuous-duty rated coils.
• Hardened precision spool and cage for long life.
• Optional waterproof E-Coils rated up to IP69K.
