    PVC diaphragm valve consists of a UPVC or CPVC body with an inlet and outlet and a diaphragm that separates these two ports. When the valve is in the closed position, the diaphragm seals against the body, preventing the flow of fluid.

    Tips: Is a diaphragm valve a ball valve?

    A diaphragm valve and a ball valve are two distinct types of industrial valves used to control the flow of fluids within pipelines, and they have fundamental differences in their design and operation.

    A diaphragm valve uses a flexible diaphragm, typically made of rubber or a similar material, to isolate the flow path. When the valve is closed, the diaphragm is pressed against the valve seat to block the flow completely. This design makes diaphragm valves excellent for applications requiring a high level of sealing and where contamination must be prevented, such as in the pharmaceutical and food industries.

    In contrast, a ball valve employs a spherical ball with a hole in it to regulate the flow. When the valve is open, the ball's bore aligns with the pipeline, allowing fluid to pass through, and when it's closed, the ball rotates to block the flow. Ball valves are known for their quick, reliable shut-off capability and are commonly used in various industries, including oil and gas, plumbing, and industrial processes.
