What is the significance of boiler safety valves?

The significance of safety valves in a boiler system is primarily to prevent overpressure within the boiler. Safety valves are engineered to automatically open and release steam when the pressure inside the boiler exceeds a preset limit. This function is critical because excessive pressure can lead to catastrophic failures, such as boiler explosions, which can result in severe damage to the equipment, injury, or loss of life.

By discharging steam when necessary, safety valves maintain operational safety and ensure that the boiler operates within its designed pressure limits. This protective mechanism is a fundamental safety feature in all steam boilers and is mandated by various safety standards and regulations governing boiler operation.
