At what pressure is the master air lock trip valve set in automatic boiler controls?

In automatic boiler controls, the master air lock trip valve is typically set to engage at 65 psi. This setting is crucial for maintaining safe and efficient operation of the boiler system. At this pressure, the trip valve helps to protect the boiler from exceeding operational limits, ensuring that any irregularities in system pressure or flow are addressed promptly.

Operation at this predefined pressure is important because it allows for optimal performance of the boiler and protects against potential hazards. By having the valve set at 65 psi, the system can maintain safe operating conditions while allowing for efficient heating and steam production.

Choosing the correct pressure is vital for ensuring that the boiler operates within its designed parameters and avoids issues such as overpressure, which can lead to equipment failure or safety risks. Understanding these settings is essential for operators and maintenance personnel to ensure reliability and safety in boiler operations.
