MAC Systems

Butterfly valve

MAC Systems can provide a number of options for butterfly valve automation and remote control.  This will depend on the size of the valve and the current configuration of the valve assembly.

For smaller valves, we have a gear and motor design. With this option, the manual wheel is replaced with a larger gear, which is driven by a smaller gear on a 12VDC motor. The motor control module that we have installed in our telemetry units allows a range of parameters to be monitored, measured and adjusted. This includes mm per pulse so that the unit can record the distance travelled, calibrate the open and closed positions and apply current cut off limits for the motor operation to ensure the valve is fully opened or closed and to avoid jamming of the valve.

For vertically driven valves, there are two options. One is a gear operated system and the other option is to connect to a 12VDC quarter turn actuator. With this option, we wire the quarter turn actuator to our telemetry board and modules to open and close the actuator and report open and closed positions.

With all options, via our web site, operators can remotely open and close valves, open and close valves to a specified position or percent and can include the automation of the valve within a simple time – based programme or irrigation schedule.
