FD941W Electric rectangular louvered butterfly valveDetailed product description：

Product Overview:
The FD941W electric rectangular louvered regulating butterfly valve is manufactured by welding steel plates, and has the characteristics of short structural dimensions, light weight, and easy installation. The valve has a small driving torque, flexible opening and closing, and easy operation. An oil seal retaining ring is installed on the valve body, and there is no visible gap between the sealing pairs, resulting in a low leakage rate. The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent jamming caused by thermal expansion and contraction. 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 widely used in industrial pipelines such as metallurgy, chemical engineering, power, building materials, and mining to control or regulate the medium gas.

Product usage and features:
Electric louver butterfly valves equipped with electric actuators are widely used in production processes such as building materials, metallurgy, mining, and electricity. They can automatically or manually control and regulate the flow rate of media in pipelines. The butterfly plate adopts a louver multi axis structure, with uniform liquid flow, small opening and closing torque, sensitive action, and reliable performance.
