Flanged butterfly valves are a type of valve that is widely used in industrial, commercial, and residential applications. These valves operate by rotating a disk inside the valve body, which can regulate or isolate the flow of fluid passing through the pipeline. The disk is mounted on a shaft that passes through the center of the valve body and rotates 90 degrees to open and close the valve.

Flanged butterfly valves are designed to be mounted between two flanges, which are bolted together to create a secure seal. The flanged ends of the valve are designed to match the flange dimensions of the pipeline, ensuring a tight fit and minimizing the risk of leaks.

Flanged butterfly valves are commonly used in water treatment plants, HVAC systems, chemical processing plants, and oil and gas refineries. They are also used in residential applications, such as plumbing and irrigation systems.

The main advantage of flanged butterfly valves is their ability to provide precise flow control and isolation with minimal pressure drop. They can operate with low torque, which means that smaller actuation devices can be used to operate the valve. This results in lower installation and maintenance costs, as well as increased energy efficiency.

Flanged butterfly valves are available in a range of materials, including carbon steel, stainless steel, cast iron, and plastic. The material used is dependent on the needs of the application, such as low or high temperature, corrosive media, or high pressure. The valve disk can also be made of different materials such as EPDM, Nitrile, Viton and PTFE, each suited for specific media and temperature.

In conclusion, flanged butterfly valves are an essential component in many industries and applications, providing accurate flow control and isolation. Their design ensures a secure fit between the valve and the pipeline, minimizing the risk of leaks and ensuring the reliability of the system. The choice of material and configuration should be carefully considered based on the specific requirements of the application to maximize performance, safety, and longevity.

Other remarks1

Compact structure, easy installation and disassembly, repair friendly and light weight

Other remarks2

It has a certain adjustment capability, and can be used as a control valve.

Other remarks3

With the triple-eccentric structural design, the sealing face is separated as soon as opening, so the mechanical wearing and friction between two sealing faces is eliminated during the opening and closing of butterfly plate, the operation torque is lowered, and the service life is longer.

Other remarks4

Good sealing performance of zero leakage.

Other remarks5

Wide range of application - triple-eccentric metallic sealing butterfly valves have a wide range of temperature, pressure and diameter.

Soft seated butterfly feathred with concentric design,is a reliable maintenance free and cost effective valve.with various optional elastomer material,it can ensure gas tight seal,leakage free and corrosion resistant in various applications.Seat is designed with backup rng prevents the seat from collapsing or dislodging and is easily replaceable in the field.Upon client request,this kind of valves can also be designed for DEAD END service at maximum pressure rating
