What happens if a safety valve does not close properly?

It may cause a fire

It can lead to overpressure in the boiler

When a safety valve does not close properly, it can lead to overpressure in the boiler. The primary function of a safety valve is to prevent excessive pressure buildup that could result in catastrophic failures or ruptures within the boiler system. If the valve remains open or partially open, steam can continuously escape, preventing the boiler from reaching a safe pressure and potentially allowing it to surpass its designed pressure limits.

This condition poses serious safety risks, as excessive pressure can damage equipment and jeopardize the safety of personnel and nearby structures. It is critical that safety valves are regularly inspected and maintained to ensure they operate effectively, safeguarding the boiler system from dangerous overpressure situations.
