What type of valve helps to control water flow and pressure in a system?

The pressure-reducing valve is specifically designed to control water flow and pressure within a system. Its primary function is to automatically reduce the high incoming pressure of water to a significantly lower output pressure. This is essential in systems where maintaining a consistent pressure is crucial for operation, as it helps to protect downstream equipment from potential damage caused by excessive pressure. These valves can help ensure that water flows at a safe rate that is suitable for various applications, ranging from residential plumbing to industrial processes.

In contrast, other types of valves serve different purposes. A butterfly valve is primarily used for regulating flow, but it is not specialized for pressure reduction. A check valve is utilized to prevent backflow in a system, ensuring that water flows in one direction rather than controlling flow pressure. A gate valve is designed mainly for isolation and to provide minimal resistance when fully opened, rather than adjusting or regulating flow and pressure.
