Designed for process airflow control and isolation duty
MNC Valves LimitedΒ offers damper butterfly valves for applications involving air, flue gas, ventilation, exhaust, and industrial duct flow control. These valves are selected where regulation or shut-off of non-liquid media is required in low to moderate pressure systems, process air handling lines, and industrial ducting arrangements.
Damper butterfly valves are commonly used in boilers, furnaces, air handling systems, dust collection systems, process exhaust lines, ventilation ducts, and industrial gas flow applications where practical control and dependable movement are important.
AΒ damper butterfly valveΒ is a butterfly-style valve designed primarily for controlling airflow, gas flow, exhaust flow, or duct-based media in industrial systems. It generally uses a rotating disc or blade assembly to regulate or isolate media within ducts, air lines, or low-pressure process gas systems.
This design is commonly selected where the buyer needs practical air or gas flow control, shut-off, or balancing in industrial ventilation and process systems rather than liquid-service pipeline isolation.
The disc or blade rotates within the body to control or isolate airflow, gas, or flue gas in duct and process systems.
Depending on design, the valve may operate as a simple on-off damper or as a controlled flow regulation device.
Damper butterfly valves are designed to fit industrial ducts, process air lines, and exhaust systems where space-efficient rotation control is needed.
