Industrial Diverter Valves for Duct Isolation and Volume Control
Air Systems fabricates custom tee and wye stack diverter valves in-house for industrial oven exhaust, RTO, and dust collection applications up to 1000°F.
Traditional two-damper tee configurations introduce two potential leak points, two actuators, and twice the maintenance exposure. Our diverter valve replaces that arrangement with a single flipper blade and actuator built integrally into the diverter duct body.

Why Air Systems Diverter Valves
Diverter valves in RTO, industrial oven exhaust, and concentrator systems operate under high thermal stress with zero tolerance for leakage past the blade seal.
Over 20 years designing low-leakage diverter valves for RTO, industrial oven, dust collection, and carbon concentrator systems — proprietary designs, fabricated in house, to your specifications.
Frequently Asked Questions
What is the maximum operating temperature for an Air Systems diverter valve?
Diverter valves are available with designs rated to 1000°F, with leakage maintained at less than 0.25% at that temperature.
How is the correct material of construction selected for my application?
Airstream type and design temperature determine material selection. Air Systems staff assist with proper material and design selection during the proposal process.
Are diverter valves factory tested before shipment?
Yes. Blade seal, actuator, limit switch, and any accessories or instrumentation are mounted and set at the factory prior to shipping.
What is the typical lead time for a custom diverter valve?
Typical lead time is 8 to 10 weeks after drawing approval, with expedited delivery available.
