China DN100 PN16 Butterfly Valve Lug Body Manufacturers, Factory
Product Description
- 1. The lug butterfly valve body have the same structural length with the wafer butterfly valve, so lug butterfly valve can be installed in a relatively compact space.
- 2. Lug butterfly valves usually require the use of multiple bolts and nuts to clamp the valve body between the flanges of the pipe, so they are more stable during installation and maintenance. But it will also increase installation time and bolt costs.
- 3. Lug butterfly valves can be used at the end of pipes because the threads in the lugs can be directly fixed to the bolts.
- 4. A soft seat provides complete isolation of the medium from the valve body.
- 5. Top Flange Standard ISO 5211.
- 6. Lug Butterfly Valves body are designed in accordance with API609 and tested to API598.

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.
