SYMBOL
DESCRIPTION
A solenoid-operated, 2-way, normally open, 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-SV12-21 acts as a check valve, allowing flow to pass from 1 to 2, while blocking flow in the reverse direction.
When de-energized, the poppet lifts to open the 2 to 1 flow path after overcoming the solenoid force (requires 3.4 to 10.3 bar / 50 to 150 psi). In this mode, flow from 1 to 2 is severely restricted.
Operation of Manual Override Option: To override, push and hold override button.
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.
