A solenoid-operated, 2-way, piloted, normally closed, poppet-type, screw-in hydraulic
cartridge valve, designed to function as a load holding or blocking valve in high-pressure
applications requiring low internal leakage.
When de-energized, the HSV12-20 blocks flow from ports 2 to 1. In this mode, the cartridge will
allow flow from ports 1 to 2 after overcoming the spring forces (see performance graph). When
energized, the valve will allow flow from ports 2 to 1 while severely restricting flow from ports
1 to 2.
Operation of Manual Override Option: The manual override feature is intended for
emergency use, not continuous duty operation. To operate, 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.
