China Wafer Type Butterfly Valve Ductile Iron Body Manufacturers, Exporter
Product Description
Although the single flange butterfly valve and the wafer butterfly valve have the same structural length, in terms of installation method, the single flange butterfly valve is bolted to the pipe flange. The single flange butterfly valve has many bolt holes and the connection is more stable.
Single-flange butterfly valve has only one flange. Compared with double-flange butterfly valve, the material cost and manufacturing cost are lower, so the price is more economical and affordable.
Single flange butterfly valve has only one flange connection. Compared with double flange butterfly valve, the overall structure is simpler and takes up less installation space.
Single-flange butterfly valves only require one flange connection. Compared with double-flange butterfly valves, the installation process is simpler, saving time and effort.
Single flange butterfly valve can be applied to some simple pipeline systems, especially for situations where one side is fixed.

A single flange butterfly valve body is a main component of the single flanged butterfly valve, is a type of valve used to control the flow of a fluid in a piping system. It consists of a disc that rotates around a central axis which allows for quick and efficient flow control.
Single flange butterfly valves are commonly used in various industries such as water treatment, sewage treatment, chemical processing, and power generation. They are also used in HVAC systems and in shipbuilding.
Some of the advantages of a single flange butterfly valve include its lightweight and compact design, low pressure drop, ease of installation, and low maintenance requirements. As its FTF is the same with wafer butterfly valve.
The temperature range for a single flange butterfly valve depends on the material of construction. Generally, they can handle temperatures ranging from -20°C to 120°C, but higher temperature materials are available for more extreme applications.
Yes, single flange butterfly valves can be used for both liquid and gas applications, making them versatile for a wide range of industrial processes.
Yes, single flange butterfly valves can be used in potable water systems as long as they are made from materials that comply with the relevant drinking water regulations and standards, so we get the WRAS certificates.
