M1500 is an electro-mechanical actuator for the control of two-way and three-way plug valves in:
• domestic hot water systems
• heating systems
• air handling systems
M1500 is either controlled by an increase/decrease 3-point floating 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.
For Satchwell valves use L2SV linkage (see accessory).
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 a position indicator signal 2-10 V and a 16 V DC voltage supply for older TAC controllers.
