Electric butterfly valve classification

Commonly used electric butterfly valves include wafer type electric butterfly valves and flange type electric butterfly valves. Wafer type electric butterfly valve uses double-head bolts to connect the valve between two pipeline flanges. Flange type electric butterfly valve is equipped with flanges on the valve, and the two ends of the valve are flanged to the pipeline flange with bolts.

Features of electric butterfly valve

(1) Adopting double eccentric structure, with tighter and tighter sealing function, and reliable sealing performance.
(2) The sealing material is made of stainless steel and nitrile oil-resistant rubber, which has a long service life.
(3) The rubber sealing ring can be located on the valve body or on the butterfly plate. It can be applied to different characteristics of media for users to choose.
(4) The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.
(5) The overall baking varnish can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is replaced.
(6) This valve has a two-way sealing function, and it is not controlled by the flow direction of the medium during installation, and is not affected by the spatial position. Can be installed in any direction.
(7) It has the advantages of small size, light weight, reliable performance, simple matching, and large flow capacity, which is especially suitable for clean liquids and gases.

Frequently Asked Question

Do you have any question?

Electric butterfly valves belong to a variety of electric valves and electric regulating valves. It is an important execution unit in the field of industrial automation control. Main purpose: Control of flow, pressure and temperature of various industrial automated production pipelines. For example: electric power, metallurgy, petrochemical, environmental protection, energy management, fire fighting system, etc.

Different. Electric butterfly valves belong to a variety of electric valves and electric regulating valves. It is suitable for occasions that require flow adjustment. Solenoid valve is an industrial equipment controlled by electromagnetic, used in industrial control system to adjust the direction, flow, speed and other parameters of the medium.

The electric butterfly valve is composed of a valve composed of an electric actuator and a butterfly valve, so it has the advantages of simple operation and simple structure of the butterfly valve, and is also widely used in chemical, pharmaceutical and other industries. The working principle of the electric butterfly valve: the valve stem is driven by an electric device to make the butterfly plate produce a 90° rotation movement to achieve the opening and closing of the valve.
