3.3.4 Servomotors with Autoflame Valves
On threaded valves, the pin on the top of the valve is 90 degrees opposite from the position of the butterfly
valve.
On flanged valves, the pin on the top of the valve is in line with the position of the butterfly valve.
For both valves the external visual position indicator is in line with the position of the butterfly valve.
Regardless of the type of valve being used, the servomotor is dispatched from the factory with the
potentiometer in the zero position. The same servomotor will be correct for both types of valve, as the
servomotor for the threaded valve is mounted at 90 degrees different from the flanged valve.
