The Macon Motorized Actuator can be used on all Macon Valves (NT series 2-way valves, EDV 3-way mixing valves, EKV cooling valve and OPSK one pipe steam valve). For controllers with continuous output in conjunction with single-room control systems. Automatic valve adjustment and intelligent cutoff for maximum energy efficiency.

The motorized actuator MPV is performed by a 0-10 V DC control signal from a room thermostat or a building management system. After switching on the power supply, the actuator initializes. The initialization of the actuator determines the mechanical stroke of the actuator. In this period the display alternately shows ”In” (for initialization) and the control voltage applied to it.
First, the valves pressure plate is fully retracted, whereby the upper end-stop of the drive is determined. Following the valve plate extends fully and determined the bottom end stop. The closing point of the valve is detected.
Next, the valve stroke recognition will happen. The actuator moves with high speed to the upper position and back to the lower position slowly, in order to determine the valve stroke. In case of not sensing the valve, the actuator will work with the factory setting stroke (8,5 mm)
The stroke of the valve can be changed in practice by different conditions. The valve was adjusted, or the actuator was mounted to a new valve. In both cases, the data obtained at the initialization values has changed. Thus, the actuator adjusts to the new valve stroke, the power supply and the control voltage must be interrupted briefly. After the power has been switched on again, the actuator performs the re-initialization phase.
NOTE! For initialization MPV needs about 15 minutes.
The motorized actuator MPV is performed by a 0-10 V DC control signal from a room thermostat or a building management system. The control signal allows a precise activation and positioning of the actuator. A 0-10 V or PWM signal can be applied to the control voltage input for control purposes.
