The HSV12-28X is a high pressure 2-way, piloted, poppet-type, normally closed, bi-directional, screw-in hydraulic cartridge valve designed to function as a load holding or blocking valve in applications requiring low internal leakage bi-directionally.
When energized, the HSV12-28X allows flow in both directions. When de-energized, the valve blocks flow in both directions.
Manual Override Operation
For normal operation (de-energized) the manual override pin must be seated in the lower detent groove. To shift the valve manually, the operator pushes down on the knob and rotates 180 degrees in either direction. When the manual override is actuated, increased flow CAN be achieved by pulling on the knob.
note: the manual override feature is intended for emergency use, not for continuous-duty operation.
