Servomotor for control valves 

Servomotors MZ are designed to operate VF, VFT and VFH butterfly valves and LMV linear modulating valves.
MZ2 and MZ3 types are suitable for basic adjusting position, operated by cams connected to driving shaft.
MZ5 type is suitable for advanced adjusting position, controlled by analogue signals with very high positioning precision.
MZ5 consists of a multi-stage spur gearbox with DC motor, driven by an electronic control unit. This allows a high torque and adjustable running time.
MZ, connected to VF, VFT, VFH butterfly valves and LMV linear modulating valves, is suitable for stage control (MZ2 and MZ3) or electronic positioning control (MZ5), of gas and air flow in combustion processes.
On request, available ATEX version (MZ.X) and/or 10Nm torque (MZ510, MZ310 and MZ210).
