Diverter Valves

Automatic “Tee” and “Wye” Stack Low Leakage Diverter Valves

Air Systems offers diverter valves that are custom designed for in-stack volume control or duct system isolation applications.  The Air Systems diverter valve is our own special design eliminating the traditional two automatic dampers mounted in a “Tee” duct section and utilizes only one “flipper” blade damper and actuator integrally built into a diverter duct body.  We build our diverter valves in a wide range of shapes, sizes and materials of construction.

Our Diverter Valve design offers the following distinct advantages:

  • Custom design based on the application requirements
  • Available in mild steel, stainless steel and special alloy construction
  • Up to 1000F design available
  • Available for ultra-low leakage – less than 0.25%
  • Factory insulation and cladding of diverter body available
  • Maintenance friendly design

Air Systems has over 20 years of combined experience designing low leakage diverter valves, offering our customers industry leading drawing and delivery lead times.

QUESTION: What materials are available for the construction of my diverter valve?
ANSWER: Carbon Steel, Stainless Steel or Special Alloy

QUESTION: How do I choose what material to use for my application?
ANSWER: Type of airstream and design temperature determine the material of construction. Our
experienced staff will assist in selecting the proper diverter design and material selection during the proposal process.

QUESTION: what is the highest temperature your Diverter can operate at with less than 0.25% leakage.
ANSWER: 1000F

QUESTION: Can you provide an adjustable blade seal
ANSWER: Yes, both our metal and tadpole seat designs are field adjustable

QUESTION: what actuators do you use
ANSWER: we can supply electric, pneumatic or hydraulic actuators sourced from global manufacturers

QUESTION: Are the diverters factory tested prior to shipping
ANSWER: Yes, we mount and set the blade seal along with the actuator, limit switch and any accessories or instrumentation at the factory

QUESTION: What is a normal Diverter Valve lead time
ANSWER: Typically, 8-10 weeks after drawing approval but we do offer expedited delivery
