Which type of valve allows for precise flow control in piping systems?

The globe valve is specifically designed for applications that require precise flow control. Its structure features a spherical body with an internal baffle that creates a flow path that can be adjusted by moving the valve disc. This configuration allows for throttling, which is the ability to finely adjust the flow rate through the valve. Additionally, the design reduces pressure drop across the valve when it is partially open, making it suitable for applications where a consistent flow rate is crucial.

In contrast, ball valves and gate valves are primarily intended for on/off control rather than precise flow regulation. Ball valves provide a quick shut-off but do not excel in flow control at intermediate positions, while gate valves are designed to be fully open or fully closed, making them inefficient for throttling applications. Check valves are utilized to prevent backflow in a system and do not allow for any flow control adjustments at all. Thus, the globe valve is the appropriate choice for achieving meticulous flow control in piping systems.
