DESCRIPTION
A solenoid-operated, 2-way, normally closed, proportional, poppet-type, screw-in hydraulic cartridge valve for blocking or load-holding applications.
OPERATION
When de-energized, the SP16-20 acts as a check valve, allowing flow from 1 to 2, while blocking flow
from 2 to 1. When energized, 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.
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_pdf.
FEATURES
• Continuous-duty rated coil.
• Efficient wet-armature construction.
• Manual override options.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.

RECOMMENDED ELECTRONIC CONTROLLERS
The EVDR Series controllers are recommended for use with most HydraForce proportional valves. These newer electronic controllers are versatile, reliable, and easily configured and customized for a wide range of applications. See the EVDR Product Selection Guide.
