What is wafer butterfly valve？
A wafer butterfly valve is a type of butterfly valve that is designed to be installed between two flanges using bolts or studs. This type of valve is called a "wafer" valve because it is very thin and has the same face-to-face dimensions as the flanges it is mounted between, making it more compact and lighter in weight than other types of valves.
Wafer butterfly valves consist of a disc that rotates around a shaft to control the flow of fluid in a pipeline. When the valve is closed, the disc is perpendicular to the flow, blocking the passage of fluid. When the valve is open, the disc rotates parallel to the flow, allowing fluid to pass through the valve.
Wafer butterfly valves are commonly used in limited space and weight applications, such as in HVAC systems, water treatment plants, and food and beverage processing industries. They are also used in applications requiring quick and easy installation and removal, such as in emergency shut-off systems.

Quality Control Process
Standards&Features:
Wafer butterfly valves offer several advantages over other types of valves, including:
1. Compact and Lightweight:
The wafer butterfly valve is thin and has the same face-to-face dimensions as the flanges it is mounted between, making it more compact and weightier than other valves. This makes it easier to install and saves space.
2. Easy to Install and Remove:
Wafer butterfly valves are easy to install and remove since they only require a few bolts or studs to hold them in place. This makes them ideal for emergency repairs or quick valve replacement.
3. Low Pressure Drop:
The streamlined design of the wafer butterfly valve results in a low pressure drop across the valve, reducing energy consumption and lowering operating costs.
4. Cost-Effective:
Wafer butterfly valves are cost-effective compared to other types of valves, making them ideal for use in applications where cost is a major consideration.
5. Versatile:
Wafer butterfly valves can be used in a wide range of applications, including HVAC systems, water treatment plants, and food and beverage processing industries, among others.
6.Easy to Operate:
Wafer butterfly valves are easy to operate since they require only a quarter-turn to open or close, making them ideal for applications requiring a frequent operation.
