Sensor-controlled or electronically operated automatic drain valves are designed to help eliminate the possiblility of fowling that sometimes occurs with a float controlled automatic drain valve. Sensors when triggered send information to the electronic control to release the condenstate. These operations are automatic and there is zero air loss during the condensate discharge cycle. Electronic drain valves are typically less likely to foul since the condensate doesn't come in contact with the sensor.
