DESCRIPTION
A solenoid-operated, two-way, normally open, direct-acting, spool-type, screw-in
hydraulic cartridge valve designed to function as a bidirectional blocking valve
in low fl ow circuits.
OPERATION
When de-energized, the SV08-25 allows fl ow in both directions.
When energized, the valve’s spool shifts to close bidirectionally.
Operation of Manual Override Option: To override, push button in and twist counter-
clockwise 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 valve function, push button in, twist clockwise 180°, and release.
Override will be detented in this position.
FEATURES
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Effi cient wet-armature construction.
• Both ports may be fully pressurized.
• Cartridges are voltage-interchangeable.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Unitized molded coil design.
• Compact size.
