描述

Round air door is also called circular baffle door, circular shut door and circular adjusting door. Circular air door is mainly used in power plant duct and flue for intercepting or regulating medium flow. It can also be used in other industries of duct and flue. The circular air valve can make the whole flow/truncation of the medium in a certain pipeline of the system or the flow rate of the medium vary with the control. For the small diameter circular valve, it has two functions: closing and regulating medium flow. For the large diameter circular valve, its regulating function is not obvious, and its closing function is mainly used.

According to the performance, it can be divided into circular shut-off door and circular regulating door; according to the driving mode, it can be divided into manual circular valve, electric circular valve and pneumatic circular valve; according to the manufacturing process, it can be divided into casting circular valve and welding circular valve; according to the material, it can be divided into cast iron circular valve, carbon steel circular valve and stainless steel circular valve. In addition, our company has developed multi-blade single-baffle circular valve, multi-blade double-baffle circular valve, as well as circular flue gas baffle door (flue-way baffle door) specially for the entrance, exit and bypass of flue gas desulfurization system.
