Which type of valve is commonly used to control water flow in plumbing systems?

The globe valve is commonly used to control water flow in plumbing systems due to its design, which allows for precise regulation of flow. This type of valve features a spherical body with an internal baffle that directs flow in a way that can easily be adjusted by turning the valve handle. This mechanism helps to achieve fine control over the flow rate, making it ideal for applications where precise adjustments are necessary.

Globe valves are particularly effective in scenarios where the flow needs to be throttled or where a consistent flow rate is critical. Their design allows for a good sealing capability, enhancing the valve's performance when it is fully closed or fully open. This attribute, along with their versatility in handling various fluids, supports their prevalence in plumbing and other related applications.

In comparison to other types of valves, such as ball valves and gate valves, the globe valve stands out in terms of flow control. While ball valves offer quick on/off control and gate valves provide minimal resistance when fully open, they are not as effective for throttling purposes. The objectives of different applications and the need for control often dictate the choice of the valve; thus, the globe valve is frequently preferred in situations requiring specific flow regulation.
