What is a diaphragm valve?

quality inside and outside

Diaphragm valve is a type of valve used to control the flow of fluids, typically gases or liquids, in a pipeline. It operates by moving a flexible diaphragm into or out of contact with a seat, which controls the flow of the medium. The diaphragm is a flexible membrane that separates the flow medium from the mechanical components of the valve, providing a leak-proof seal when the valve is closed.
