Which type of valve operates similar to a diaphragm valve?

The globe valve operates similarly to a diaphragm valve because both types of valves regulate flow by controlling the distance between two sealing faces. In a diaphragm valve, the flow is controlled by a flexible diaphragm that moves up and down to open or close the valve. Similarly, in a globe valve, the flow is adjusted by a disk that moves vertically along the stem to either block or allow fluid passage through the valve body.

This design allows for precise control of flow rates, making globe valves suitable for applications where throttling is necessary. The shape of the globe valve body also contributes to its ability to manage pressure drops efficiently while maintaining flow control, much like the function of a diaphragm valve.

Other valve types, such as butterfly, ball, and stop valves, do not operate in this same manner. Butterfly and ball valves primarily offer on/off control with less efficient throttling capabilities, while stop valves refer generally to valves that stop flow rather than to a specific design type like the globe valve.
