Wafer butterfly valve

It is critical to understand the differences between a wafer butterfly valve and a lug-style valve when purchasing a new valve or replacing an existing valve. You will also need to know how a wafer valve works and what materials are used to make them. You'll also need to know how much a wafer valve costs and what kinds of actuators can be used with them.

Common uses for butterfly valves

Butterfly valves are commonly used to regulate the flow of media. They can be made of a number of different materials. Stainless steel, carbon steel, and copper alloy are examples of common materials. The type of material used is determined by the application. Exotic materials are employed in some applications.

ASTM A216 WCB alloy is the most common material used in butterfly valves. This alloy must contain at least 10.5% chrome. This material is appropriate for applications requiring high heat resistance as well as corrosion resistance. In addition, it is used in high-temperature applications. It is not suitable for use in seawater.

Butterfly valve also make use of stainless steel and PTFE. In most cases, PTFE is used in weak acid applications. It is also suitable for brine applications.

Cost of a wafer butterfly valve

A Wafer Butterfly Valve is an excellent choice for many industrial applications. This type of valve  such as butterfly lug type has good flow characteristics and takes up little space. However, it is critical to select the appropriate size for the application. The material for the disc and seat is also determined by the application.

Wafer butterfly valves are frequently less expensive than other types of valves. They are also simple to maintain. They have a good seal and can be used with pneumatic and electric actuation. They do not, however, provide as much flexibility as other types of butterfly valves.

Another drawback of wafer butterfly valves is that they are not suitable for end-of-line applications. They also have a limited flow control range. Nonetheless, they remain a popular choice for a wide range of industrial applications.
