Product Description

Product introduction

The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent the phenomenon of sticking caused by thermal expansion and cold contraction. The valve can be equipped with a variety of driving devices, such as manual device, worm gear transmission device, pneumatic device, electric device. Ventilation butterfly valve is widely used in metallurgy, chemical, electric power, building materials, mining and other industrial pipelines, the medium gas gas control or regulation.
