What is the main purpose of a safety valve?

The main purpose of a safety valve is to prevent overpressure in a system. Safety valves are critical components designed to automatically release excess pressure from boilers and other pressurized systems to ensure that the pressure does not exceed safe operating limits. This automatic operation protects equipment, enhances safety, and prevents potentially dangerous situations, such as explosions or structural failures due to excessive pressure buildup.

While controlling flow rates, reducing temperatures, and monitoring pressures are also important functions in various systems, they are not the primary function of a safety valve. The specific role of a safety valve is narrowly focused on overpressure protection, ensuring that the pressure remains within a safe range for operation. This is essential in maintaining the integrity of the system and safeguarding personnel and equipment.
