Is it true that a safety valve may NOT have a valve on its discharge piping?

True
False
Only for certain types of systems
Only if a bypass exists

The correct answer is: True

A safety valve is a critical component of a boiler system that is designed to release excess pressure to prevent catastrophic failures. For safety valves to function effectively, they must have an unobstructed discharge path that allows for immediate release of steam or pressure. Having a valve on the discharge piping can create a serious safety hazard; if the valve were to close, it would prevent the safe release of pressure, rendering the safety valve ineffective. This could lead to excessive pressure buildup within the system, potentially resulting in equipment damage or even explosions. Therefore, regulations and best practices dictate that safety valves should not have any valves in their discharge piping to ensure that they can operate without obstruction at any time when the pressure exceeds safe levels. This aligns with industry standards meant to enhance the safety and reliability of boiler operations.
