Which valve is located nearest to the boiler on the feed water line?

The globe valve is frequently located nearest to the boiler on the feed water line due to its design, which allows for precise flow regulation. This is especially important in boiler applications, where maintaining the correct water level and flow rate is critical for safe and efficient operation. The globe valve’s shape and internal structure enable it to provide a throttling capability that is superior to other types of valves, making it the ideal choice for controlling the feed water supply.

In addition, globe valves excel at maintaining a steady flow despite variations in pressure. Their ability to handle high temperatures and pressures also aligns well with the operational conditions found near a boiler. This valve type can effectively manage the feed water entering the boiler, ensuring that the system operates smoothly and minimizing the risk of issues such as water hammer or inadequate steam production.

While check valves, ball valves, and gate valves have their respective uses in piping systems, they are generally not as suited for the regulatory role near a boiler. Check valves are typically used to prevent backflow and are not intended for flow control, ball valves provide quick shutoff but are not ideal for throttling, and gate valves are primarily designed for on/off services without flow regulation. This makes the globe valve the most effective and appropriate choice for placement
