The Diaphragm Valve is a type of valve that controls the flow and direction of fluids or gases using a diaphragm instead of a movable stem or ball. This makes it more suitable for use with corrosive, abrasive, or dirty media. It operates smoothly with minimal friction due to the lack of mechanical parts touching the fluid. The 2-way diaphragm valve has two ports allowing fluid to flow in either direction and can be operated manually or automatically by an air pressure signal. This valve is important in plumbing systems as it allows for precise control of fluid flow, minimizes wear and tear on pipes, and resists the build-up of residues.
