The Expello® Electronic Drain Valve for air tanks is an automatic, maintenance-free drain valve that provides constant protection from build-up of harmful contaminants in air tanks on trailers, buses, trucks and other vehicles.

The Expello Electronic Drain Valve expels contaminants every five minutes of vehicle operation with a powerful one-second blast of air. The electronic controls and 15-watt heater provide all weather, year round protection.

The Expello valve's corrosion-resistant construction ensures maintenance-free protection over the long haul. Once installed in place of your manual drain petcock, the Expello valve’s straight-through contaminant flow and self-cleaning design provides long-term air tank draining without daily checks. Brakes and other air-operated systems consistently receive cleaner, dry air when contaminants are removed from air tanks, thus extending component service life.

The Expello Electronic Drain Valve for air tanks consists of a powerful heavy-duty coil, a long-life timer with a built-in surge protection and a 15-watt thermostatically controlled heater. The valve is protected by internal fuses. All components of the Expello Electronic Drain Valve are covered by a one – year unlimited mileage warranty.
