FAQ
What is a butterfly valve?
A butterfly valve is a type of flow control device used to regulate or isolate fluid flow in a pipeline. It utilises a rotating disc to allow, restrict, or block flow. When the valve is fully closed, the disc blocks the pipeline entirely.
How does a butterfly valve work?
The butterfly valve operates by rotating a disc around its axis. Depending on the disc’s position, the valve can be fully open, partially open, or fully closed, controlling the fluid flow through the pipeline. The disc is connected to an actuator, which can be manually operated or powered.
