Frequently Asked Questions

What is the purpose of the anti-ice control valve?

The anti-ice control valves help manage the system by controlling the airflow from the pneumatic system into the ducts of the plane’s boots. When turned on, the de-ice control valves open, and the deflate valve energizes and closes, routing pressurized air through the control valves and into the boots.

Ultimately, the control valves run the mechanical system to ensure ice breakup on wings.

How do inflate and deflate valves help regulate air?

Inflate and deflate valves regulate air when the plane is not in use. Deflate valves deflate the air from the boots to allow the biggest change in size when the boots are inflated. Simple de-ice systems often don’t use more than one deflate and inflate valve. When the valve closes, the boots are delivered air. When the valve closes, air deflates through vacuum pressure.

This function is often built into other parts of the de-ice system, like the distributor valve.
