OEM DN800 DI Single Flange Type Wafer Butterfly Valve Manufacturers, Exporter
Product Description
A single flange butterfly valve refers to the structure of the valve body, which consists of a flange longitudinally surrounding the center of the valve body and installed by connecting to a flange on the pipeline. The butterfly plate can adjust the flow of fluid by rotating 90 degrees or less, thereby opening, closing, or regulating the fluid in the pipeline.
This type of butterfly valve is commonly used to control fluids in industrial pipelines, especially for large-diameter pipelines (DN300 or greater) and low-pressure systems. They are often used in air ducts, the chemical industry, water supply and drainage systems, cooling water systems, and several other uses. Single flange butterfly valves are designed to be easy to install and maintain and are a common choice in many industrial piping systems.
Streamlined, lightweight profile engineered for ease of installation and low-maintenance operation.
Rapid opening and closing response enabled by an efficient 90-degree rotational disk stroke.
Reliable sealing performance designed for rigorous industrial fluid and low-pressure systems.

A single flange 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.
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.
