What is the primary function of a type UV pressure safety valve in a steam system?

The primary function of a type UV pressure safety valve in a steam system is to protect against excessive pressure. This valve is a critical safety component that opens automatically to release excess pressure from the steam system, thereby preventing potential damage to the equipment and reducing the risk of accidents. The safety valve is designed to ensure that the pressure within the system remains within safe limits.

When pressure reaches a predetermined set point, the valve opens to allow steam to escape, which reduces the pressure and stabilizes the system. This mechanism is essential for maintaining safe operating conditions and preventing catastrophic failures that can occur if pressure is allowed to exceed safe thresholds. By fulfilling this protective role, the UV pressure safety valve helps ensure not only the safety of the steam system but also the safety of personnel working in or around the system.
