SAUNDERS Type A Diaphragm Valve (Weir Design)
A diaphragm valve is a bi-directional, on-off throttle valve used to control fluid flow by regulating the area through which the media can enter and exit the valve. This effectively changes the fluid’s speed and velocity. Known for their excellent sealing capabilities and resistance to corrosion, diaphragm valves are ideal for applications requiring sanitary conditions and chemical resistance. They are widely used in industries such as pharmaceuticals, food and beverage, water treatment, and chemical processing. Diaphragm valves are easy to clean and maintain, making them suitable for processes that require frequent sterilization and high purity standards.
