SL08-22 Low Flow, 2-Way, Normally Closed
DESCRIPTION
A solenoid-operated, 2-way, normally closed, direct-acting, needle-type, screw-in
hydraulic cartridge valve, designed to function as a load-holding device for low fl ow
circuits requiring extremely low leakage.
OPERATION
When de-energized, the SL08-22 blocks fl ow from ➁ to ➀.
When energized, the needle point lifts to open the valve bidirectionally.
Operation of Manual Override Option: To override, push button in, twist counter-
clockwise 180° and release. In this position, the valve will remain open.
To return to normal operation, push button in, twist clockwise 180° and release. Over-
ride will be detented in this position.
FEATURES
• Continuous-duty rated solenoid.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Industry common cavity.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Compact size.
