SV38-31J Valve

SYMBOL:
SV38-31J Valve symbol
DESCRIPTION
A solenoid-operated, 3-way, spool-type, screw-in hydraulic directional cartridge valve.

OPERATION
When de-energized, the SV38-31J allows flow from 2 to 1 while blocking flow at 3.
When energized, the cartridge’s spool shifts to open flow from 1 to 3, while blocking 2.
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.

FEATURES
• 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.
• Unitized, molded coil design.
• Manual override option.
• Optional waterproof E‑Coils rated up to IP69K.
• Industry common cavity – Compact size.
