A valve installed in each medical gas and vacuum piping system shall be tested to verify which of the following?

• A. Pressure Range
• B. Flow and pressure drops
• C. Date of installation
• D. Proper operation and rooms or areas of control

Answer: (D)

The key idea is to confirm that a valve in the medical gas and vacuum piping system works as it should and controls the correct zones. Valves are used to isolate or supply gas to specific rooms or areas, so testing focuses on whether the valve moves properly, indicates its position correctly, and actually affects the intended area when opened or closed. In practice, you would actuate the valve and verify that the gas supply to the designated rooms is controlled as designed, and that any interlocks or room-control signals respond appropriately. This ensures patient-care areas receive gas only when the valve is in the proper state and that zone control is reliable. While pressure ranges or flow/pressure drops relate to broader system performance, they are not the primary objective of validating valve operation for the targeted rooms or areas. Date of installation is not relevant to functional performance.
