Electric shutter round (window) valve
The electric louver circular (window type) valve is used in conjunction with an electric actuator and has the advantages of small opening and closing torque, sensitive action, reliable performance, large diameter and light weight. Electric louver circular (window type) valves are widely used in fans, air conditioners, electric dust collectors, and various large pipelines in industrial sectors such as metallurgy, building materials, power, petrochemical and light industry, which can automatically or manually adjust and cut off dust and gas.
