Butterfly valves are quarter-turn rotary valves that use a disc-shaped closure element to block or allow the flow of fluids through a pipeline. The disk is mounted on a shaft that passes through the center of the valve body and is connected to a handle or lever on the outside of the body that can be used to open or close the valve.
The amount of rotation required to open or close the valve depends on the design of the valve but is typically between 90 degrees and 180 degrees. When the disk is in the closed position, it covers the opening in the valve body and blocks the flow of fluid through the pipeline. When the disk is in the open position, it uncovers the opening and allows fluid to flow through.
When properly installed and maintained, butterfly valves purchased from quality butterfly valves suppliers can provide reliable service for many years. However, like all mechanical components, they are subject to wear and tear and may eventually need to be replaced.
One of the most common problems that can occur with butterfly valves is leakage. This can be caused by a number of different factors, including wear and tear on the seats or seals, damage to the disk or shaft, or improper installation.
Another common problem is binding or sticking, which can be caused by dirt or other debris build-ups on the disk or shaft, or by damage to the disk or shaft. Choosing a high-quality product from the most trusted butterfly valves that suppliers can help to limit the likelihood of this happening.
With this information in mind, you’ll be able to choose the right butterfly valve for your needs and keep it in good working condition for many years to come.
