MZ20A is a zone actuator designed to provide modulating control together with VZ*19* zone valves.

The M20A actuator is used in fan-coil-units, induction units, small reheaters and recoolers, and for zone control applications.

Actuators are available in two modulating versions:
- MZ20A with a selectable command range
- MZ20A-R 0-10 V only

Reliable long-time operation is ensured from no mechanical feedback potentiometer and no mechanical end switches. Automatic synchronization function provides self adjusting close off.

Based on a full stroke running time of 100 s, valve positioning and flow adjustment is very exact.
