Which valve is used to control flow and pressure in a water distribution system?

• A. Foot valve
• B. Globe valve
• C. Butterfly valve
• D. Air release valve

Answer: (B)

The globe valve is designed specifically to control flow and pressure within a water distribution system. Its unique construction, featuring a movable disk and a stationary ring seat, allows for precise regulation of the flow rate. This makes it particularly effective for applications where throttling and flow control are necessary. The spherical shape of the globe valve allows it to effectively reduce pressure drops, making it a preferred choice for controlling flow in various systems. In addition to its flow control capabilities, globe valves are also capable of withstanding high pressures, which is essential in many water distribution applications. This ability to adjust the flow rate and maintain pressure stability is crucial for ensuring that the system operates efficiently and effectively delivers water to its intended locations. Other types of valves serve different purposes in water distribution systems. For example, the foot valve is typically used at the bottom of a pump suction line to prevent backflow, while the butterfly valve is often used for on/off control and isolation rather than precise flow regulation. An air release valve, on the other hand, is designed to remove trapped air from the system to prevent pressure build-up, rather than to control flow or pressure directly.
