SV08-30 Valve

SV08-30 Valve symbol
A solenoid-operated, 3-way, spool-type, screw-in hydraulic directional cartridge valve.

When de-energized, the SV08-30 allows flow from 2 to 1 while blocking flow at 3. When
energized, the cartridge’s spool shifts to open from 3 to 2, while blocking flow out 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, twist counterclockwise 180°.
The internal spring will push the button out. In this position, the valve may be only partially shifted.
To assure full override shift, pull the button out to its fullest extension and hold it in this position.
To return to normal operation, push button in, twist clockwise 180°, and release. Override will be
detented in this position.

• Continuous-duty rated coil.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• All ports may be fully pressurized.
