MVA actuators are used in V-ZB globe valve coupling for
cool/warm water control in two and four pipe terminal
units and zone systems.
MVT4 actuator is designed to provide, with VST and VSBT
valve bodies, floating control of hot/cool water in
two/four-pipe fan-coil units, zone and solar plants, reheat
coils and dehumidification batteries.
The MVT5 actuator is designed to provide proportional
control of both VST and VSBT valve bodies in fan-coil
units, solar plants, reheaters and recoolers using hot
and/or cold water.
These actuators are equipped with a reversing
synchronous motor and an electronic board available in
three different models respectively for:
- floating control
- proportional control (d.c. voltage or current)
Due to their versatility these actuators can be mounted
both on new ‘Controlli’ globe valves up to DN 2” as well
as on different manufacturers valves, with stroke from
10.8 to 20mm.

Series SH actuators are used in air conditioning,
thermoventilation, heating systems and in industrial
processes to drive dampers.
