SP10-25 Proportional, Spool, 2-Way, Normally Closed (SP10-25)
A proportional solenoid-operated, two-way, spool-type, normally open, bi-directional, screw-in hydraulic cartridge valve.
Product Operation
When de-energized, the SP10-25 allows flow from 2 to 1 or from 1 to 2. 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.

Graphs based on 12 VDC “D” coil current.
NOTE: Curves shown are at constant pressure. Limiting flow to the valve or significant changes in dif-ferential pressure will change valve performance. Without a pressure compensator, the valve requires a minimum of 250 psid to achieve stable control of the spool as shown on the flow vs. current graphs.
