How to choose an electric butterfly valve?

Selection Guide for Electric Butterfly Valve

As an important control device, electric butterfly valves are widely used in multiple fields. When selecting, multiple factors need to be considered to ensure their stable and efficient operation.

Clearly define the operating conditions

Firstly, the usage scenario of butterfly valves should be considered. In general industrial pipelines, if the medium is common fluids such as water and air, ordinary material electric butterfly valves may be sufficient. But if the medium is corrosive, such as acid or alkali solutions, then corrosion-resistant butterfly valves should be selected, such as stainless steel electric butterfly valves, which can effectively resist corrosion and extend the service life of butterfly valves. At the same time, it is necessary to determine the working pressure and temperature range. Electric butterfly valves of different specifications can withstand different pressures and temperatures. Overpressure or overheating can cause damage to the butterfly valve and even lead to safety accidents.

Determine the connection method

The common connection methods for electric butterfly valves include flange connection, clamp connection, and welding connection. The flange connected electric butterfly valve is relatively easy to install and disassemble, and is suitable for situations where the pipeline diameter is large and requires frequent maintenance; The electric butterfly valve with clamp connection has a compact structure and occupies a small space, and is commonly used in pipeline systems with limited space; The electric butterfly valve connected by welding has good sealing performance and is suitable for high temperature and high pressure working conditions. According to the actual pipeline connection requirements, selecting the appropriate connection method can ensure a good connection between the butterfly valve and the pipeline, avoiding leakage.

Consider control requirements

There are various control methods for electric butterfly valves, including switch type, regulating type, etc. The switch type electric butterfly valve is mainly used for on/off control of pipelines, with simple operation; Adjustable electric butterfly valves can precisely adjust parameters such as flow rate and pressure of the medium. If fine control of flow is required, a regulating electric butterfly valve should be selected. In addition, the performance of electric actuators, such as control accuracy and response speed, should also be considered to meet different control requirements.

In short, the selection of electric butterfly valves is a process that comprehensively considers usage conditions, connection methods, and control requirements. Only by selecting the appropriate electric butterfly valve can the stable operation of the system be ensured and production efficiency be improved.
