Square butterfly valve; Widely used in cold air, air and flue gas pipelines of hot blast furnaces, heating furnaces, heat exchangers, dust collectors and other systems in metallurgical systems, it can be remotely controlled or operated on site. Valves with different performance can be combined with worm gear devices or electric (pneumatic) devices.

Working principle and structural characteristics of square butterfly valve:

The square butterfly valve is a globe valve, mainly composed of valve body, butterfly plate, connecting rod, driving device and other components. The working principle of the valve is that the output torque of the driving device is transmitted through the valve shaft and connecting rod mechanism to rotate the butterfly plate from 0 to 90 degrees, which plays a role in cutting off or circulating the medium. This valve is not recommended for regulating the medium. Welded with carbon steel plates. It has the characteristics of light weight, good rigidity, compact structure, temperature resistance, no wear on the sealing surface, and small air leakage.
