Easy to operate | Electric butterfly valve | Affordable

Electric butterfly valves are suitable for occasions that require flow adjustment. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it is about three times that of the gate valve. Therefore, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the strength of the butterfly plate to withstand the pressure of the pipeline medium should also be considered when it is closed. sex. In addition, it is necessary to consider the limitation of the working temperature of the elastic valve seat material at high temperature.

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.

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.
