APPLICATION AND USE
VSBT two-way and VMBT three-way valves can be used
for fluid control in industrial and residential air-condition-
ing, thermoventilation and heating plants and in product
thermal process machinery.
Three-way valves must be used only as mixers, angle way
must never be employed for control purposes.
ACTUATORS
VSBT and VMBT valves are actuated by CONTROLLI MVT
actuators.
∆Pmax = max differential pressure ensured by the actuator
for normal operation.
100 Kpa = 1 bar
OPERATION
The valve is normally closed (A-AB way).
By pushing the stem inwards, the actuator opens A-AB
way and, in three-way valves, it contemporarily closes the
angle way B-AB.
MANUFACTURING CHARACTERISTICS
G25 cast iron valve body.
Brass plug with Contoured-type profile on direct way and
V-port profile on angle way.
CrNi steel stem. Female threaded connections.
Double BUNA O-ring stem packing.

INSTALLATION
Before mounting, ensure pipes are clean, free from weld
slag, perfectly aligned with the valve body and not sub-
jected to vibrations.
As far as valve mounting positions are concerned, follow
the instructions given in the actuator data sheets.
While mounting, respect the fluid directions indicated by
the letters on the valve body (see fig. 1 and 2).

APPLICATION
MVT actuator is designed to provide, with V.XT, V.T and V.BT
valve bodies, floating control of hot/cool water in two/four-pipe
fan-coil units, zone and solar plants, reheat coils and dehu-
midification batteries.
OPERATION
POSSIBLE COMBINATIONS AND
CONNECTIONS
MVT actuators are to be used with CONTROLLI V.XT, V.T, V.BT
valves.
The MVT28/44 series can be connected to any 3-position con-
troller, with characteristics corresponding to details included
in the paragraph “TECHNICAL CHARACTERISTICS”.
The MVT5. series is standard proportional as indicated on table
1. Due to the presence of the magnetic clutch, the actuator
could be continuously powered up without damages but, for
life increase and energy saving, it is highly reccomended to
use a controller equipped with a cut-off function (suggested
timing 120% of stroke time).
MANUFACTURING CHARACTERISTICS
The actuator consists of a base and a housing made of syntetic
materials which contain motor, gear box, magnetic coupling,
valve driving screw spindle.
A ring nut M30x1.5 is placed on the lower part; it allows an easy
coupling to the valve without special tools.
The actuator is equipped with a cable for 3-wire electrical con-
nection. It requires no maintenance.
Stroke timing 100 s for V.T valves having
5,5 mm stroke (at 50 Hz)
Speed 18 s/mm at 50 Hz - 15 s/mm
at 60 Hz
Force 200 N (UNI 9497)
Temperature:
- working -5T55 °C
- storage -25T65 °C
Protection class III (IEC 950)
Connecting cable 3-wire 1,5 m (CEI 20-22/II)
Protection degree IP43 CEI EN 60529
Weight 0,2 Kg.
The product conforms to EMC 89/336 directive with
reference to the below-mentioned standards:
for emission EN 50081-1 for immunity EN 50082-1
INSTALLATION AND MOUNTING
The actuator can be mounted in the positions indicated below.
Before assembling the actuator to the valve, remove the pro-
tection cap from valve and make sure that the actuator screw
spindle corresponds to the upper notch on the base plate (fac-
tory supplied position). Otherwise, it is advisable to consider
that, in order to mount the actuator on the valve correctly, the
force of the valve internal spring will have to be overcome.Then
it should be fixed by tightening the M30X1,5 ring nut on the
thread located on the valve body (Fig. 1).
Mounting positions allowed
MVT actuator is electric bidirectional.
The valve stem movement is produced by rotation of a screw
spindle connected, through a gear train, to a synchronous bidi-
rectional motor.
An internal magnetic hysteresis coupling limits the torque on
the valve stem, avoiding the usage of microswitches and pro-
tecting the actuator from overload.
N4038
Perform the electrical connections in compliance with existing
rules (Fig. 2)
Through the slits located by the ring nut, it is possible to ob-
serve the valve stem movement.

RANGE AND ACTION SELECTION
The actuator is supplied with 0..10 V- signal and direct action.
In case a different setting is required:
•Remove the rubber plug (see the figure below)
• Switch on ‘ON’ position the DIP 2..8 corresponding to the
required range.
• Direct action: Position DIP N.1 on OFF
Screw spindle lowers if signal increases (for 3-way valves
the direct way is opened and for 2 way-valves it opens).
•Reverse action: Position DIP N.1 on ON
Screw spindle raises if signal decreases (for 3-way valves
the direct way is closed and for 2 way-valves it closes).
•Replace the rubber plug in the previous position.

MVT28/44
Supply the controller-actuator system, after having mounted
the actuator on the valve body and once the electrical
connections are performed and the action ranges selected.
When powered, the actuator reaches one stroke end and
remains in this position for about 2 min. Afterwards, the actuator
will reach the position set by the controller signal (MVT56,57).

SELECTION
It is possible to start all MVT
models with manual control by
means of a socket head key (3
mm).
It is necessary to power off
the actuator before starting
the manual control.

MVT28 actuator is supplied with a screw-safety connector
cover. We recommend to carry out the connection with the
actuator powered off. At the end of the wiring procedures mount
and screw again completely the connector.
