DESCRIPTION
A solenoid-operated, 2-way, normally closed, spool-type, direct-acting, screw-in hydraulic
cartridge valve, intended for blocking or load-holding in low flow circuits.

OPERATION
When de-energized, the SV08-24 blocks flow in both directions. When energized the spool
shifts to allow flow in both directions.
Operation of Manual Override Option: To override, push button in and 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.

FEATURES
• Bidirectional flow path.
• Manual override option.
• Screen option.
• Continuous-duty rated coil.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Both ports may be fully pressurized.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
• Compact size.
