1. Superior corrosion resistance
The hot-dip galvanized coating forms a durable zinc layer on the valve body, protecting it from rust and corrosion in humid, coastal, and outdoor environments.
2. Longer service life
Compared with ordinary painted bodies, galvanized surfaces offer stronger resistance to weathering and mechanical wear, extending valve lifespan.
3. Strong adhesion coating
The zinc coating is metallurgically bonded to the ductile iron body, reducing peeling or surface damage during transport and installation.
4. Ideal for harsh outdoor conditions
Suitable for exposed pipelines, water treatment facilities, marine environments, and infrastructure projects.
5. Low maintenance requirement
The galvanized surface reduces maintenance frequency and repainting costs over long-term operation.

About Products:
1. What is a single flange butterfly valve body?
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.
2. What are the applications of a single flange butterfly valve?
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.
3. What are the advantages of a single flange butterfly valve?
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.
4. What is the temperature range for a single flange 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.
5. Can a single flange butterfly valve be used for both liquid and gas 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.
6. Are single flange butterfly valves suitable for use in potable water systems?
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.
