Areas of use

Together with an electronic room thermostat, i.e. MMA R21 and R31 or other breaker function, MMA’s actuator can regulate all MMA’s two and three-way valves.
The actuator can be mounted on MMA’s previous valve models and even on other makes using an adapter unit
Description
The actuator has two designs:

· VMO pushes the valve’s spindle at electric current
· VMC lifts the valves spindle at electric current

Both types are available ins 230V AC and 24V AC/DC.
The position of the spindle is indicated in blue above the connecting union nut.
