Electronic timer controlled drain valves are traditionally considered less likely to foul, but less energy efficient than a no-loss valve. They are well suited for small to medium sized compressed air systems. Most electronic drain valves let you set the drain to come on once every 10 seconds to 45 minutes and remain open for 0.10 to 10 seconds.
