2 · GT 50 · Edition 10.09 GT 50 Application Gear motor GT 50 is mounted directly onto a butterfly valve, for example, DKR, in order to control the gas and air flow rates on gas burners. It is designed for applications that require precise, controlled rotary movement between 0° and 90° or 0° and 160°. There are two possible ways of checking the current position of the actuator – either using an optional feedback potentiometer or an optional current sensor. These scan functions can be used in automation processes. The GT 50 is controlled by a continuous signal or three-point step signal. The...

GT 50 · Edition 10.09 · 3 Examples of application Modulating control via three-point step signal Threepoint step VAG M GT 50 + DKR For processes that require high temperature accuracy and low circulation in the furnace. Gear motor GT 50 is controlled by a threepoint step controller and moves the butterfly valve DKR to the ignition position. The burner starts. The butterfly valve opens or closes DKR between the low-fire and high-fire rate positions depending on the capacity demand of the burner. When the three-point step signal is disconnected, the butterfly valve stops at its current...
