We offer a selection of flight-proven anti-ice valves that are designed primarily for bleeding off high temperature, compressed air from aircraft engines. These specialty valves are used for anti-icing applications as they provide reliable service at temperatures up to 900°F.

Our selection of normally open solenoid operated valves control high temperature airflow bled off from the fourth stage of a turbine engine. This airflow can be routed to engine structures or flight surfaces to elevate their surface temperatures above the level where icing can occur. Specific configurations have significant history on helicopter platforms, while other mature anti-ice valve configurations are also available.

Key features of our anti-ice valves include...

• Flight qualified in defense aircraft applications
• Normally-open / energize to close design ensures anti-ice protection through power loss
• Two-Stage design with piloted operated spool for high flow
• Thermally isolated electrical elements for continuous duty operation
• Sensing port provides positive indication of valve position
• Constructed of high temperature corrosion resistant materials
• Specially engineered to meet the requirements of each system
