Which valve is commonly used for stopping and starting flow in steam lines?

Gate valves are used for stopping and starting flow in steam lines because they provide a straight, unobstructed path when fully open for minimal pressure drop, and they seal well when closed for a tight isolation. This makes them reliable for on/off service in high-temperature steam systems. Globe valves are designed for throttling and control, so they resist flow even when more open and create more resistance than a gate valve. Check valves only allow flow in one direction and don’t provide controllable stopping and starting. Ball valves offer quick shutoff, but in steam service their seats can be stressed by heat and may not be as durable for long-term isolation as gate valves.
