Which category of valves can be found in water supply and drainage systems?

Gate, globe, and check valves all serve essential functions in water supply and drainage systems, which is why this answer encompasses the broad range of applications for these valve types.

Gate valves are primarily used for on/off services, allowing or blocking flow with minimal pressure drop when fully opened. They are ideal for systems where flow control is not frequently needed, making them common in water supply lines.

Globe valves, on the other hand, are designed for throttling and regulating flow. Their structure allows for more precise control of water flow, making them advantageous in situations requiring fine adjustments or when flow needs to be modulated.

Check valves play a vital role in preventing backflow in a system, ensuring that water flows in one direction. This is crucial in drainage systems to avoid contamination from waste back flowing into clean water sources or supply lines.

Having all three types of valves serves to regulate flow, manage pressure, and ensure safety within plumbing systems, underscoring the importance of each in various applications throughout water supply and drainage networks.
