Working principle and purpose of the product:

The electric rectangular louvered regulating butterfly valve is manufactured by welding steel plates. This valve can be equipped with various driving devices such as manual device, worm gear transmission device, pneumatic device, and electric device. Ventilation butterfly valves are used for controlling or regulating the medium gas in industrial pipelines such as metallurgy, chemical engineering, power, building materials, and mining.

Product Structure Features:

1. The butterfly plate adopts a louver multi axis structure with uniform liquid opening and closing torque, small action sensitivity, and reliable performance.

2. It has the characteristics of short structural size, light weight, and easy installation.

3. There is no visible gap between the oil seal ring and the sealing pair on the valve body, and the leakage rate is low.

4. The large expansion gap between the butterfly plate and the valve body can effectively prevent jamming caused by thermal expansion and contraction.
