A solenoid-operated, 2-way, normally closed, poppet-type, screw-in hydraulic cartridge valve, with standard and manual override options. This valve is intended to function as a load holding or blocking valve in applications requiring low internal leakage, or low-flow circuits with pull-only manual override requirements for handles or cable linkage.
When de-energized, the DHF10-221H acts as a check valve, allowing flow from 1 to 2, while blocking flow
from 2 to 1. With the sensor option, the neutral sensor will signal ON or HIGH and OFF or LOW.
When energized, the cartridge's poppet lifts to open the 2 to 1 flow path. In this mode,
flow from 1 to 2 is severely restricted. (If this path is required, see model SV10-22, page 1.044.1.)
With the sensor option, the neutral sensor will signal LOW or OFF, HIGH or ON, or BOTH for Dual redundancy.
Operation of Manual Override Option: To override, push button in, twist counterclockwise 180°,
and release. In this position, the valve will remain open. To return to normal operation, push button in,
twist clockwise 180°, and release. Override will be detented in this position.
