What is flanged butterfly valve?

A flanged butterfly valve is usually cylindrical in shape, which is typically installed in a pipe system or as an inlet or outlet to some type of closed system. Flanged butterfly valve is used to regulate the flow of some material, either liquid or granular, that acts as a fluid with respect to flow. A flange, when the word is used to refer to a butterfly valve, is a collar that is used as an anchor point for installation. The flange butterfly valve is typically pre-drilled with holes for bolts to connect the butterfly valve to other pipe sections, but some may be designed to connect to the system differently such as with clamps or latches.

What should we know about flanged butterfly valve?

The flanged butterfly valve is simple in structure, small in size and light in weight, which consists of only a few parts. Moreover, flanged butterfly valve can be opened and closed quickly by rotating 90° with simple operation. At the same time, the flanged butterfly valve has good fluid control characteristics.

The butterfly plate of the flanged butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the flanged butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the flanged butterfly valve is fully opened. When the flanged butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small.

The flanged butterfly valve has two sealing types, that are, elastic seal and metal seal. For elastic sealing flanged butterfly valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the butterfly plate.

 

What are the features of flanged butterfly valve?

Flanged butterfly valve has bidirectional sealing without flow direction of the medium.

Flanged butterfly valve body vulcanized EPDM, which is reliable sealing.

Flanged butterfly valve has a dial with an opening indication showing the position of the disc switch.

Flanged butterfly valve is small and light, which is easy to disassemble and repair.

Flanged butterfly valve can be installed in any position.

The structure of flanged butterfly valve is simple and compact, whose operating torque is small.

The connection between the butterfly plate and the flanged butterfly valve stem adopts a pin-less structure, which overcomes possible internal leakage points.

The outer circle of the flanged butterfly valve plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the flanged butterfly valve.

The seal of flanged butterfly valve can be replaced, which is reliable to achieve two-way sealing.

 

How about the future of flanged butterfly valve?

With the development of large-scale complete sets of technology, a series of new complete sets of equipment and single machines have emerged. The characteristics of the development of new complete sets of equipment related to butterfly valves are large-scale, high-parameterization, high-performance automation and complete sets, which are compatible with the control methods of these complete sets of equipment.

The control methods of flanged butterfly valves have also developed greatly. In addition to general manual, motorized, electric, pneumatic, and hydraulic transmission, the variety of flanged butterfly valves with electro-hydraulic linkage, pneumatic-hydraulic linkage, and automatic control is increasing.

Although our flanged butterfly valve industry has developed rapidly in recent years, the overall level of the flanged butterfly valve industry is still low that the flanged butterfly valve technology is low and many key flanged butterfly valves with high parameters still rely on imports. Some experts estimate that our flanged butterfly valve level is 10 to 20 years behind foreign advanced countries. Not long ago, in order to strengthen exchanges with the European valve manufacturing industry, the Chinese valve industry has organized more than 10 domestic valve companies’ heads to visit Europe and learned a lot of valuable experience from foreign counterparts.

 

Learn more something about flanged butterfly valve can know the detailed information about flanged butterfly valve and the trend of flanged butterfly valve industry. In the process of butterfly valve development, a number of very powerful companies have emerged, such as Tianjin Worlds Valve Co., Ltd. Our company knows how to innovate while developing, and will also go out in the process of introducing flanged butterfly valve.
