In a free flow direction through the inlet, the ball is unseated and the flow is out of the cylinder port. When the control valve is centered, the load is locked.

This is internally piloted.
The damped pilot piston reduces damaging shocks and has easily replaceable seats in some models.
The directional valve cylinder ports should be connected to the tank in the centre condition
