How many shutoff valves are required for each boiler in multiple boiler installations?

In multiple boiler installations, each boiler is required to have its own individual shutoff valve. This is crucial for safety and maintenance purposes. Individual shutoff valves allow for the isolation of each boiler from the system when maintenance or repairs are needed, ensuring that work can be performed safely without having to shut down the entire system.

Additionally, having individual shutoff valves helps in effectively managing the operation of each boiler independently, allowing for flexibility in maintenance schedules and reducing the potential for system failures or other issues. This requirement is typically outlined in the relevant mechanical codes and standards to ensure safe operation in various context and scenarios, reinforcing the need for individual management of each boiler’s operation and maintenance.
