MVC • Actuator for globe valves

  • Actuators

Compact actuator for globe valves

Application

MVC actuator can be used with valves push/pull (using auto stroke calibration) or with valves with spring return using fixed stroke to
control hot/cool water flow rate in two/four pipes terminal units, zone and solar plants, small reheating and dehumidification coils.

Specifications

MVC is an electrical bidirectional actuator. The valve stem is activated through a synchronous motor and a gear train optimised in
order to have high performances and minimal noise ejections. The actuator is equipped with a movement of limit force which is able
to stop the power supply when the force of 300N is reached. If configured as auto calibration stroke, the software of the proportional
models enables the stroke calibration, so it can be used on any valve, as long as it respects the maximum stroke limit allowed (look
at the above table).
