SV16-20 Valve

SYMBOL:
SV12-20 Valve symbol

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 SV16-20 acts as a check valve, allowing flow from 1 to 2, while blocking flow from 2 to 1. When energized, the cartridges poppet lifts to open the 2 to 1 flow path. In this mode, flow from 1 to 2 is severely restricted. If this path is required, see model SV16-22, page 1.046.1.
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.
