M700 is a spring return electro-mechanical actuator for the control of two-way and three-way plug valves in:
M700 is either controlled by an increase/decrease signal or by a modulating 0–10 V control signal. Modulating control makes for a faster positioning of the actuator. The electronic circuitry of the actuator ensures that the running time is the same, regardless of the stroke of the valve in question.
It is easy to mount and connect the actuator. It can be mounted directly onto TAC’s control valves, without any mounting kit. The working range of the actuator is adjusted automatically depending on the stroke of the valve. The electronic circuitry of the actuator then takes care of the adjustment of the valve end positions.
The actuator is supplied by 24 V AC. It can provide 16 V DC voltage supply for older TAC controllers.
