DASV12-21 Poppet, 2-Way, Normally Open
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 energized,DASV12-21acts 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. If this path is required, see model DASV12-23, 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.
● Manual OverrideOptions.
● Optional waterproof E-Coils rated up to IP69K.
● Cost effective cavity.
