    Pneumatic diaphragm valve applications

    Tips: How does a diaphragm valve work?

    A diaphragm valve works by using a flexible diaphragm to regulate the flow of fluid through a pipeline. The valve body is typically made of metal or plastic, and it contains two chambers separated by the diaphragm. In the closed position, the diaphragm seals the passage between the two chambers, preventing fluid from flowing through the valve.

    When the valve is actuated, a compressor or actuator pushes against the diaphragm, causing it to move upwards and away from the valve seat. This creates a flow path for fluid to pass through the valve. When the compressor is released, the diaphragm returns to its original position, sealing off the valve and stopping the flow of fluid.

    The advantage of using a diaphragm valve is that the diaphragm is a flexible component, which allows it to be used with fluids that are corrosive, abrasive, or vicious. Diaphragm valves are also easy to clean and maintain, making them a popular choice for applications that require frequent cleaning or sterilization.
