DESCRIPTION
A solenoid-operated, 2-way, normally closed, piloted poppet-type, screw-in hydraulic cartridge valve, for blocking or load-holding in applications requiring low internal leakage.
OPERATION
When de-energized, the SV16-22 acts as a check valve, allowing flow from 1 to 2, while blocking flow
from 2 to 1. When energized, the valve’s poppet lifts to allow bi-directional flow.
Operation of Manual Override Option: To override, push button in, twist counterclockwise 180°,
and release. In this position, the valve will remain open. 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 seat for long life and low leakage.
• Optional coil voltages and terminations.
• 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.
