Do you Know the Development History of Butterfly Valves?

May. 14, 2021

As a Flange Butterfly Valve Supplier, let’s learn about the development history of Butterfly Valve today!

In order to meet the use requirements of industrial applications such as high and low temperature, strong erosion, long life, etc., the metal sealing butterfly valve has been greatly developed in the past ten years.

With the application of high temperature resistance, low temperature resistance, strong corrosion resistance, strong erosion resistance, and high strength alloy materials in butterfly valves, metal sealed butterfly valves have been widely used in industrial fields such as high and low temperatures, strong erosion, and long life. The emergence of butterfly valves with large diameter (9750mm), high pressure (2.2kN/cm2), and wide temperature range (-102~606℃) has brought the technology of butterfly valves to a whole new level.

Due to the application of computer-aided design (CAD), computer-aided manufacturing (CAM) and flexible manufacturing system (FMS) in the valve industry, the design and manufacture of butterfly valves have reached a new level.

It not only completely innovated the design calculation method of the valve, but also reduced the heavy repetitive routine design work of the professional and technical personnel, so that the technicians have more energy to improve the technical performance of the product and the research and development of new products, shorten the cycle and improve Increased labor productivity. Especially in the field of metal-sealed butterfly valves, due to the application of CAD/CAM, a three-dimensional sealing pair designed by CAD and processed by cAM numerically controlled has appeared, so that the sealing surface of the valve is free from any squeezing, scratching, or abrasion during the opening and closing process. , So that the sealing performance and service life of the butterfly valve are improved by orders of magnitude.

When the butterfly valve is fully opened, it has a small flow resistance. When the opening is between about 15° and 70°, it can perform sensitive flow control. Therefore, the application of butterfly valves is very common in the field of large-diameter adjustment. Gradually become the dominant valve type.

Since the movement of the butterfly valve plate is wiping, most butterfly valves can be used for media with suspended solid particles. Depending on the strength of the seal, it can also be used for powder and granular media.
