DESCRIPTION
A solenoid-operated, 2-way, piloted, normally closed, poppet-type, bi-directional, screw-in hydraulic cartridge valve, designed to function as a load holding or blocking valve in high pressure applications requiring low internal leakage bi-directionally.
OPERATION
When de-energized, the HSV10-28 blocks flow in both directions. When energized, the valve opens to allow bi-directional flow.
Operation of Manual Override Option: 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° in either direction. When the manual override is actuated, increased flow can be achieved by pulling on the knob.
