DESCRIPTION
A solenoid-operated, 2-way, normally closed, piloted poppet-type, screw-in hydraulic
cartridge valve, intended to act as a blocking or load-holding device for low flow circuits.

OPERATION
When de-energized, the SV08-20 acts as a check valve, allowing flow from 1 to 2, while
blocking flow from 2 to 1. When energized, the cartridges poppet lifts to open the 2 to 1
flow path. In this mode, flow from 1 to 2 is severely restricted. If this path is required, see
model SV08-22, page 1.041.1.
Operation of Manual Override Option: To override, push button in, twist counterclockwise 180,
and release. In this position, the valve will remain open. To return to normal operation, push button in,
twist clockwise 180, and release. Override will be detented in this position.

FEATURES
Continuous-duty rated coil.
Hardened seat for long life and low leakage.
Optional coil voltages and terminations.
Cartridges are voltage interchangeable.
Unitized, molded coil design.
Manual override option.
Optional waterproof E-Coils rated up to IP69K.
Industry common cavity.
Compact size.
