MZ
Servomotor for butterfly valves 
Servomotors MZ are designed to operate VF and VFH butterfly valves. They consist of a multi-stage spur gearbox with DC motor, driven by an electronic control unit. This allows a high torque and adjustable running time. MZ3 type is suitable for basic adjusting position, operated by cams connected to driving shaft.
