What type of safety valves are typically used in these systems?

Safety valves used in high-pressure boiler systems are designed to automatically release pressure that exceeds a predetermined limit to prevent potential explosive failures. The pop-spring type of safety valve is the most commonly utilized in these applications due to its specific design characteristics.

The pop-spring safety valve operates by using a spring to hold the valve disc tightly against the valve seat under normal conditions. When the pressure inside the boiler exceeds the set limit, the force of the gas or steam pressure lifts the valve disc off its seat, allowing the excess pressure to escape. This immediate response is crucial in high-pressure systems, as it ensures that the boiler remains within safe operating limits.

This type of safety valve is favored because it provides reliable and quick action to release pressure, making it extremely effective in preventing dangerous situations. Its design is specifically tailored for the rapid opening and closing necessary for high-pressure conditions, thus enhancing the safety of the entire boiler system.
