A solenoid-operated, 2-way, normally closed, poppet-type, screw-in hydraulic car-tridge valve, designed to function as a load holding or blocking valve in applications requiring low internal leakage.
When de-energized, the SV16-20 acts as a check valve, allowing flow to pass from ➀ to ➁, while blocking flow in the reverse direction.When energized, the poppet lifts to open the ➁ to ➀ flow path. In this mode, flow from ➀ to ➁ is severely restricted. If this path is required, see model SV16-22, page 1.046.1.
Operation of Manual Override Option: To override, push button in, twist counter-
clockwise 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.
• Continuous-duty rated solenoid.
