Installation and start-up information
Direction of rotation versus
flow
NOTE:
The V12, V14 and T12 motors are
bi-directional.
V12 rotation:
- End cap position T (AC, AD and AH
controls): When port B (open arrow) is
pressurized, the motor rotates clockwise
(right hand; R), and when port A (black
arrow) is pressurized, the motor turns
counter clockwise (left hand; L)
- End cap position M (EO, EP, HO and
HP controls): A and B port positions inter-
change (A-to-B, B-to-A).
V14 rotation:
- Refer to the V14 illustration below right
(valid for all compensators and controls).
T12 rotation:
- Refer to the V14 illustration below right.
NOTE:
Before installing a V12, V14 or
T12 motor in series (when both
A and B ports can be subject to
high pressures simultaneously)
contact Parker Hannifin.
