SYMBOL
DESCRIPTION
A solenoid-operated, 2-way, normally closed, poppet-type, screw-in hydraulic cartridge valve, designed to function as a load holding or blocking valve in applications requiring low internal leakage.
OPERATION
When de-energized, the E-SV12-20 valve acts as a check valve, allowing flow to pass from port 1 to port 2, while blocking flow in the reverse direction. When energized, the poppet lifts to the port 2 to port 1 flow path. In this mode, flow from 1 to 2 is severely restricted.
Operation of Manual Override Option: Rotate the knob counterclockwise for 2 turns, 2 to 1 open; rotate the knob clockwise for 2 turns to return to the normal state.
FEATURES:
* Continous-duty rated coil.
* Hardened seat for long life and low leakage.
* Optional coil voltages and terminations.
* Efficient wet-armature construction.
* Cartridges are voltage interchangable.
* Unitized, molded coil design.
* Manual override option.
* Optional waterproof E-Coils rated up to IP69K.
* Industry common cavity.
* Compact size.
