A wafer butterfly valve is a type of quarter-turn valve that controls the flow of fluids in a pipeline. It is called a "wafer" valve due to its slim, wafer-like profile, which allows it to be sandwiched between two pipeline flanges without the need for additional flange bolts
The wafer butterfly valve consists of a thin, disc-shaped closure element known as the "butterfly" that pivots around a central shaft. The disc is mounted in the center of the valve body and is typically made of metal or a resilient material such as rubber or PTFE.
The valve body is usually constructed from materials like cast iron, ductile iron, stainless steel, or carbon steel, depending on the application requirements.
The valve's slim profile and lightweight design make it easy to install and suitable for use in space-constrained areas.
Wafer butterfly valves are used in a variety of piping systems to regulate the flow of liquid or gas between two points. Hey provide efficient and reliable operation by allowing for quick on/off control, as well as precise regulation when necessary. Wafer butterfly valves are relatively simple to install and operate, making them a popular choice for many applications. In this article, we'll explore the basic workings of wafer butterfly valves, different types available, installation tips and more.
These valves are typically installed in pipelines that receive frequent use and must be trusted for reliable performance. Wafer butterfly valves consist of a disc mounted on the end of a stem connected to an actuator such as a hand wheel or motor.
When the valve is opened, the disc swings away from the line, creating an unrestricted path for the flow through the middle of the valve. When closed, the disc's edges come into contact with either side of the line, blocking it off completely. This design helps to ensure tight shut-off without having to install any additional seals or packing materials. The ease of installation and simple design make wafer butterfly valves a popular choice for many applications, providing cost savings over other control valves due to their shorter installation time and low maintenance requirements.
