Which type of valve is used to control the flow of gases at various points in the medical gas system?

• A. Zone valve
• B. Pressure relief valve
• C. Ball valve
• D. Check valve

Answer: (A)

The zone valve is designed specifically to control the flow of gases at designated points in a medical gas system. This type of valve enables healthcare facilities to isolate sections of the gas supply for maintenance or emergencies, ensuring that gas flow can be controlled selectively. It allows for efficient management of the gas system, effectively maintaining safety and functionality within various zones of a healthcare facility. While other types of valves serve important roles, they do not perform the same function of flow control at various specific points in the system. For example, pressure relief valves are used to release excess pressure to protect the system, ball valves are typically used for on/off control rather than flow regulatory control in a more nuanced system, and check valves ensure unidirectional flow but do not control flow rate. Therefore, the zone valve is distinct in its capability to manage and control the flow of medical gases across different areas as needed.
