diverter Damper Valves

We offer Diverter Damper Valves (DDV) in sizes from 150mm to 3000 mm in round shape and Square/ Rectangular Shape and Pressure rating up to PN 1. Different Sealing materials for 99.95% leak tightness are offered as per application requirement. As the name suggests it has one inlet and two outlets with one or two Flaps. Flow is coming from inlet and getting diverted to Outlet 1 or Outlet 2 as per the application requirement. Our Diverter Damper valves are designed for control and Isolation of Various nature of Flowing media like Flue Gases, Dusty, Corrosive, hazardous etc. Having Design temperature from -25

Deg. C to 825 Deg. C.
