What is a wafer butterfly valve?

Wafer butterfly valves have been around for a long time, and are used for a variety of applications. Wafer butterfly valves made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, the wafer butterfly valve's name is based on the functionality of its disc. Wafer butterfly valves are classified as "quarter-turn" valves. When the metal disk that's part of the wafer butterfly valve's design is rotated a quarter of a turn, it opens or closes.

What you should know about the wafer butterfly valve?

The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the wafer butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°, which can play a role in flow adjustment. When the butterfly plate of the wafer butterfly valve rotates to 90°, the valve reaches the maximum opening. The wafer butterfly valve is simple in structure, small in size, light in weight, and consists of only a few parts. Moreover, the wafer butterfly valve can be opened and closed quickly by rotating 90° with a simple operation. At the same time, the wafer butterfly valve has good fluid control characteristics.

The wafer butterfly valve usually has just two or four unthreaded holes to secure and align the valve within two mating flanges. The wafer butterfly valve is placed between pipe flanges, and the flange bolts surround the valve body. A wafer type butterfly valve is easy to installed but it cannot be used as an isolation valve.

What are the functions of the wafer butterfly valve?

One of the functions of wafer butterfly valve is to retain a seal to protect against dual-directional pressure differential in the flow of fluid. In other words, the wafer version of wafer butterfly valves was designed to hold a tight seal, safeguarding against bi-directional pressure differential in order to avoid any backflow in systems that have been manufactured for uni-directional flow. This is accomplished by using a tightly fitted seal, such as an O-ring, gasket, precision machined, along with a flat valve face on the downstream and upstream sections of the valve.

l Flow regulation: flow can be easily controlled or regulated simply by turning the wheel of wafer butterfly valve. Using a flow controller the process can be automated.

l Flow isolation

l Prevention of backflow: wafer butterfly valves can be used for backflow prevention in some situations.

How about the development of the wafer butterfly valve?

The wafer butterfly valve industry is an important branch of our general machinery. Wafer butterfly valves are widely used in petroleum, chemical, metallurgy, electric power, urban construction, environmental protection and other industries as key equipment for fluid control. At present, the wafer butterfly valve production industry is in a very favorable development opportunity.

Investment in fixed assets has gradually expanded, especially the projects such as West-East Gas Transmission, West-East Electricity Transmission, and South-to-North Water Diversion projects, which require a large number of wafer butterfly valves. 

With the entry of WTO, the lowering of the international trade threshold and the adjustment of product structure in developed countries, China is gradually becoming the world's largest processing plant. The processing and production of wafer butterfly valve products is facing greater room for development.

l Actively promote the joint reorganization of butterfly valves enterprises. Build a batch of large-scale and high-grade enterprise groups.

l Attach importance to the adjustment of wafer butterfly valves’ structure.

l Implement a diversified sales strategy, striving to open up the international market and expanding wafer butterfly valves’ exports.
