SYMBOL
DESCRIPTION
A solenoid-operated, 2-way, piloted, poppet-type, normally open, screw-in, hydraulic cartridge valve designed for low leakage in load-holding applications.
OPERATION
When de-energized, the E-SV10-21 allows flow from port 2 to port 1. Flow from port 1 to port 2 is severely restricted in this mode. When energized, the valves poppet closes on its seat, blocking flow in the port 2 to port 1 direction. In this mode the cartridge will allow port 1 to port 2 flow after overcoming the solenoid force (requires 50 to 150 psi [3.4 to 10.3 bar]).
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.
