Introduction to Diaphragm Valves
Diaphragm valves are a type of valve that use a flexible diaphragm to control the flow of fluid. The diaphragm is typically made of rubber, elastomer, or other flexible materials. When the valve is open, the diaphragm is lifted, allowing the fluid to flow through the valve. When the valve is closed, the diaphragm is pressed against the valve seat, preventing the fluid from passing.
Diaphragm valves are widely used in various industries, including chemical processing, pharmaceuticals, food and beverage, water treatment, and semiconductor manufacturing. They offer several advantages, such as excellent corrosion resistance, tight shut - off, low maintenance requirements, and the ability to handle abrasive and viscous fluids.
