DASV10-21 Poppet, 2-Way, Normally Open

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，DASV10-21 allows flow from 2 to 1 .Flow from 1 to 2 is severely restricted in this mode. If the 1 to 2 path is required, see model DASV10-23,When energized, the valve’s poppet closes on its seat, blocking flow in the 2 to 1 direction. In this mode the cartridge will allow 1 to 2 flow after overcoming the solenoid force (requires 3.4 to 10.3 bar / 50 to 150 psi). Operation of Manual Override Option: To override, push and hold override button.

FEATURES

● Continuous-duty rated solenoid.
● 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.
● Industry common cavity.
● Manual OverrideOptions.
● Optional waterproof E-Coils rated up to IP69K.
