Manifold Valve Operation
The manifold valves operate as follows:
1. Hydraulic pressure is applied to the P
(pressure) fitting of a valve.
2. A solenoid coil (item 2) is energized by
an 18V -32V DC signal.
3. The coil forces the 3-position solenoid
spool to move. This is illustrated in the
section of the graphic labeled “energized
position”.
4. Fluid flows from the center pressure line
out to the cylinder.
5. A pilot pressure pushing on the check
valve opens the return path.
