3. For butterfly valves with bypass valves, the bypass valve should be opened before opening.

4. It should be installed according to the installation instructions of the manufacturer, and a solid foundation should be set for the butterfly valve with large weight.

With the development of electric valves, there are many well-known valve companies at home and abroad to produce electric valves, and electric butterfly valves are important execution units in the field of industrial automation control. It belongs to a variety of electric valves and electric control valves. It is widely used in textile, power station, petrochemical, heating and refrigeration, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other fields.

This product can be used as shut-off valves, control valves and check valves in piping systems. Complete manual controls, electric or pneumatic transmissions, can meet the specific conditions of different working conditions. Meets the most stringent quality requirements for very long-lasting applications.

Especially in the metallurgical steel and shipbuilding industries, it has a very high reputation.

Electric butterfly valves are suitable for applications where flow regulation is required. Because the pressure loss of the butterfly valve in the pipeline is relatively large, about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the firmness of the butterfly plate to bear the pressure of the pipeline medium when it is closed should also be considered. In addition, the limitations of the operating temperature to which the elastomeric seat material can be subjected at high temperatures must also be taken into account.

The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics, and the structural principle of the butterfly valve is most suitable for making large-diameter valves. When a butterfly valve is required to be used to control the flow rate, it is important to select the correct size and type of butterfly valve so that it can work properly and effectively. In general, the midline butterfly valve requires a short structural length and a fast opening and closing speed (1 4 revolutions) in throttling, regulation control and slurry media.

Low pressure cut-off (small pressure difference), butterfly valve is recommended. Butterfly valves can be used when there is a small amount of leakage into the atmosphere and abrasive medium in the case of double-position adjustment, necked ground channel, low noise, cavitation and gasification, a small amount of leakage to the atmosphere, and abrasive medium. When the butterfly valve is used under special working conditions, such as throttling adjustment, or strict sealing, or serious wear, low temperature (cryogenic) and other working conditions, it is necessary to use a special butterfly valve with metal seal with adjustment device.

Introduction: Usually everyone may have less understanding of electric butterfly valves, because there is less contact, so there is not much understanding, but the application of electric butterfly valves is indeed more and more extensive. Today, let me take you to have an in-depth understanding of the electric butterfly valve.

Look at what kind of characteristics he has.

Introduction to electric butterfly valves

Electric butterfly valves have a very good development situation at present, and now there are many well-known enterprises producing electric butterfly valves. Electric butterfly valve is more and more widely used in our lives, with its development, its product performance is getting better and better, and the after-sales service is becoming more and more perfect, so it is highly praised and favored by our customers.

There are two types of connection methods for electric butterfly valves: flange type and clamp type. Its connection method plays a very important role in the field of industrial automation. As long as the application field of electric butterfly valve is:

Textile, petrochemical, pharmaceutical, shipbuilding, light industry, power station and so on. Shut-off valves, check valves, and control valves in the piping system can all be done with electric butterfly valves. Electric butterfly valves have strict quality requirements, so they can have a long trial period.

In the metallurgical steel and marine industries, electric butterfly valves have a very high reputation.

In situations where flow regulation is required, an electric butterfly valve is very necessary. In the selection of electric butterfly valves, it is enough to consider many aspects, not only to consider the influence of the pressure of the pipeline system on the electric butterfly valve, but also to consider the pressure of the pipeline medium that the butterfly plate can withstand in the closed state, and the working temperature that the elastic valve seat can withstand at high temperatures should also be taken into account. The length and overall height of the electric butterfly valve are relatively small, and it has very good flow performance.

When the electric butterfly valve is used to control the flow, it is necessary to carefully select the type and size of the butterfly valve, so as to ensure that the electric butterfly valve can give full play to its advantages and work.

Electric butterfly valve features:

1. The sealing performance is very reliable, and the double eccentric structure is adopted, so that it can be tighter and tighter.

2. Stainless steel and nitrile oil-resistant rubber are used as secondary raw materials for sealing, so his service life is relatively long.

3. The sealing rubber ring can be placed in different positions and can be used in different media, so that customers can choose according to their own wishes.

4. The butterfly plate adopts a frame structure, which has a large flow area, good strength, and less resistance during circulation.

5. The electric butterfly valve is small in size, light in weight, and very simple to match, which is suitable for those gas and liquid disturbances where the medium is relatively clean.

After the introduction, we have a further understanding of the electric butterfly valve and a more comprehensive understanding. The application of electric butterfly valve has become more and more extensive, and it is believed that it will have a good development prospect.
