PILOT TO SHIFT - 3W CLOSED TRANSITION

Mechanical Directional Control Valves
Pilot to Shift
3 Way Closed Transition
In neutral the valve allows flow between ports (3) and (4), port (2) is blocked
With application of a remote pilot signal at (5), the valve's spool shifts to allow flow between ports (2) and (3), while port (4) is blocked.
During transition all ports are closed
The spring chamber is vented to the tank through port (1)
The vented spring chamber allows the valve to be fully pressurized at ports (2), (3), and (4) without affecting required pilot preasure
Pressure at (1) will affect required pilot pressure
