SV38-31J Spool, 3-Way
DESCRIPTION
A solenoid-operated, three-way, direct-acting, spool-type, screw-in hydraulic cartridge
valve.
OPERATION
When de-energized, the SV38-31J allows fl ow from ➁ to ➀, while blocking fl ow at ➂.
When energized, the cartridge’s spool shifts to open from
➀ to ➂, while blocking at ➁.
While port
➀ 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°. 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
• Continuous-duty rated solenoid.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Effi cient wet-armature construction.
• Cartridges are voltage interchangeable.
• All ports may be fully pressurized.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Unitized molded coil design.
• Compact size.
