PILOT TO SHIFT - 3W OPEN TRANSITION

Mechanical Directional Control Valves
Pilot to Shift
3 Way Open 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 ports (2), (3), and (4) are open
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
