The Features of Electrically Operated Butterfly Valve:
1 Adopting the non-pinning structure, it can effectively prevent the pin from falling off in long-term operation.
2 This electrically operated butterfly valve has a two-way sealing function, which is not controlled by the flow direction of the medium during installation, and is not affected by the spatial position. Electric wafer butterfly valve can be installed in any direction.
3 The sealing accessory material is matched with stainless steel and nitrile oil resistant rubber to effectively extend the service life.
4.The structure is simple and compact, and the 90° rotation is quick to open. The pressure difference is small and the circulation capacity is large. Electrically operated butterfly valve has low operating torque and is labor-saving. It can be used for regulating or on/off control.The electric soft seated butterfly valve is equipped with manual device.
5.It has very significant economy, especially for larger diameter butterfly valves. (Butterfly valve is preferred for medium and low pressure applications). Superior economic performance makes electrically operated butterfly valve widely used in industrial automatic control systems for food, environmental protection, light industry, petroleum, paper,chemical,marine,water supply and drainage,electric power and other industries.
