Why is a ball check valve installed in the bottom cutout valve of the gage glass?

• A. It allows for manual operation
• B. It prevents the escape of hot water in case the gage glass breaks
• C. It enhances the gage glass visibility
• D. It reduces the pressure in the system

Answer: (B)

The installation of a ball check valve in the bottom cutout valve of the gage glass is primarily for safety and operational integrity. When a gage glass breaks, there is a risk of hot water escaping from the system, which can lead to hazardous conditions, including burns, equipment damage, and loss of pressure. The ball check valve serves as a protective mechanism that automatically seals off the gage glass from the system. When water attempts to escape through the opening created by the broken gage glass, the ball in the check valve will move to block the flow, preventing hot water from leaking out. This design feature enhances safety by containing the water and reducing the likelihood of an incident. While the other choices discuss functionalities such as manual operation, visibility enhancement, and pressure reduction, they do not correctly align with the primary safety purpose of the ball check valve in this context. The focus is on preventing hot water from escaping, which is crucial to maintaining safe operational conditions within the system.
