INTRODUCTION
The Dual Pilot Operated Check Valve locks the
hydraulic cylinder in position, preventing it
from drifting down or failing if the hydraulic
circuit loses pressure.
The pilot valve closes once the oil flow from
the control valve stops. Applying pressure to
the pilot port opens the check valve poppet
and the oil leaves the cylinder. This works in
either direction of cylinder travel. Install the
valve between the directional control valve
and the cylinder.
