Analogue or 2-point or 3-point gear motors

Servomotors MZ operate VF, VFT, VFH butterfly valves, and LMV linear modulating valves.

MZ2 and MZ3 types are suitable for basic adjusting positions, operated by cams connected to the driving shaft.

MZ5 type is suitable for advanced adjusting position, controlled by analog signals with high positioning precision.

MZ5 consists of a multi-stage spur gearbox with a DC motor driven by an electronic control unit, allowing 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.


Available on request: ATEX version (MZ.X) and/or optional 10Nm torque (MZ510, MZ310 and MZ210).
