APPLICATION AND USE

MVE is a flexible electro-mechanical actuator for the control of two
and three way globe valves in:
• heating and cooling systems
• Air Handling Units
• district heating plants
• industrial temperature control systems.
MVE can be controlled either by a proportional (modulating) signal
or by an increase/decrease (Floating) signal.
It is easy to mount and connect the actuator. Direct mounting is pos-
sible to any CONTROLLI flanged valve. Linkage kits are available for
CONTROLLI threaded valves as well as for valves of other manufac-
turers (table page 3).
The actuator has a fine resolution (500 steps on the full stroke range)
for exacting fluid control and it is able to self-calibrate on a different
stroke without the need of any user action (this function is DIP switch
selectable on the field).
MVE has intelligent behaviour and alarm functionality in case of un-
expected operation, feedback of alarms to the user is provided by
LEDs (GREEN and RED) on the control board.
N.B.: Do not use the actuator if not coupled with its relating valve.

OPERATION

The actuator translates the control signal (modulating or 3 point
floating) from the controller into a valve position. A modern brushless
DC motor in the actuator drive a gear train and a worm gear – screw
jack mechanism convert the motor revolutions into accurate and
repeatable linear movements.
Control Signal
MVE can be controlled by one of 2 main control types.
• 3 point floating;
• modulating (or proportional) signal with field selectable range
(e.g., 0-10Vdc, 2-10Vdc, 0-5/2-6Vdc, 5-10/6-10Vdc and 4-20mA).

Manual Override
There is a manual operation handle on the actuator. When it is low-
ered (manual override ON), the power supply to the motor power
stage circuitry is cut and the motor stops. The actuator can be op-
erated manually and the valve positioned accordingly. The manual
override lever latches in position until it is raised again, then board
and motor will be powered again. At the end of this operation the
actuator moves to initial position (on the basis of DIP n. 1 setting) then
it follows the control signal. When the manual override is engaged
the GREEN and the RED LED are ON.
Manual operation handle can also be used to modify any DIP switch
setting or as re-set function after any alarm occurrence. The actua-
tor is supplied with the manual override lowered (ON).
t is not necessary to remove power supply to modify DIP switch set-
ting, but, in this case, take care of 230Vac voltage.
Feedback position
The actuator utilizes a 2-10V position feedback (look at DIP n. 1 set-
ting).
Calibration
The actuator has both auto and manual stroke calibration, DIP n. 7.
In factory delivery the auto stroke calibration is enabled – manual
calibration is not necessary unless maintenance is required on the
valve or certain alarm functions are desired.
