What type of fluids are diaphragm valves primarily used for?

Diaphragm valves are specifically designed for applications involving corrosive and toxic fluids due to their construction and functionality. The diaphragm, typically made from flexible materials, separates the fluid from the moving parts of the valve. This design minimizes the risk of leaks and contamination, making diaphragm valves suitable for handling aggressive chemicals that could cause damage to conventional valves or create health hazards.

In addition, the smooth flow path provided by diaphragm valves reduces the chances of any particles accumulating within the valve, which is particularly important when working with hazardous substances that require precise control and safety measures. This capability enhances their usability in chemical processing and other industries where corrosive or toxic fluids are prevalent.

Other choices may not encompass the full range of applications for diaphragm valves. For example, while non-corrosive fluids can be handled, diaphragm valves are not limited to this category. Similarly, restricting the use to only water or gas would not reflect their versatility in handling a wide range of fluids in various industrial settings.
