  • The Importance Of Safety Valves On Steam Boiler - …

    In steam boilers, safety valves are typically used for boiler over-pressure protection and other applications. Especially for power generation boilers that produce high pressure steam, the safety valves are very important. The safety valve operates by reducing the excess pressure in a safe manner when a predetermined maximum pressure is reached.
