What is the purpose of having an isolation valve in the vacuum piping system?

The purpose of having an isolation valve in the vacuum piping system is primarily to isolate the system for maintenance. This feature is essential for ensuring safety and operational integrity. When maintenance or repairs are required, it is critical to prevent any vacuum system components from being unintentionally engaged or affecting surrounding equipment. Isolation valves allow technicians to safely work on a section of the system without shutting down the entire system.

Additionally, these valves help to contain the vacuum within a specific section, preventing disruptions in other areas of the system, which can be particularly important in facilities where multiple systems operate simultaneously. This enhances both safety for the maintenance personnel and continuity of operations for the overall medical gas system, ensuring patient care is not compromised during maintenance activities.
