Is an automatic shutoff valve allowed between the boiler and the water column?

An automatic shutoff valve between the boiler and the water column is not permissible due to safety and operational concerns. The water column plays a critical role in providing accurate water level readings within the boiler. If an automatic shutoff valve were to malfunction or close unexpectedly, it could result in a situation where the water level cannot be monitored or controlled properly. This could lead to over-pressurization or overheating of the boiler, presenting significant risks, including potential equipment damage or catastrophic failure.

Safety codes and regulations governing boiler operations typically prohibit the installation of any valve that might interrupt the flow of water between the boiler and the water column, thus ensuring continuous monitoring and management of water levels. Compliance with these safety standards is crucial for maintaining the integrity of boiler systems and protecting personnel and property.

In contexts where manual isolation of the water column is required for maintenance or troubleshooting, strict protocols govern the use of such valves. However, the key point is that automatic shutoff valves do not allow for the necessary level of control and safety required in the operation of a boiler system.
