SYMBOL
DESCRIPTION
A solenoid-operated, 3-way, direct-acting, spool type, screw-in hydraulic directional valve.
OPERATION
When de-energized, the E-SV08-30 allows flow from port 2 to port 1, while blocking flow at port 3. When energized, the cartridges spool shifts to open from port 3 to port 2, while blocking flow out port 1. While port 1 may be fully pressurized, it is not intended to be used as the inlet.
Operation of Manual Override Option: To override, push button in and 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 detended in this position.
FEATURES:
* Continous-duty rated coil.
* Hardened seat for long life and low leakage.
* Optional coil voltages and terminations.
* All ports may be fully pressurized.
* Efficient wet-armature construction.
* Cartridges are voltage interchangable.
* Unitized, molded coil design.
* Manual override option.
* Optional waterproof E-Coils rated up to IP69K.
* Industry common cavity.
* Compact size.
