The butterfly plate of butt welding butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0 and 90 degrees. When it rotates to 90 degrees, the valve is fully opened.Butt welding butterfly valve The wafer butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed only by rotating 90 degrees, and the operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. Butterfly valve has two sealing types: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate.
Wafer butterfly valves offer several features that make them an ideal choice for a variety of applications. First, they are designed for maximum efficiency and reliability by providing tight shut-off without the need for additional seals or packing materials.
Additionally, they feature low torque requirements while still achieving high flow rates. Furthermore, wafer butterfly valves typically come with a built-in positive sealing system, which helps ensure proper operation regardless of temperature changes or pressure fluctuations Another benefit is their easy installation due to their compact size and two-piece design which eliminates the need for welding or any other specialized equipment. Their design also makes them suitable for most media such as liquids, gases, and steam, making them an ideal solution for many industrial applications.
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.
