Which valves should not be located in a room with station outlets or inlets that they control?

The inclusion of zone valves in a room with station outlets or inlets that they control is not advisable due to safety and operational concerns. Zone valves are designed to control the flow of medical gases to specific areas or zones and should be located in areas that are easily accessible for maintenance and monitoring without the risk of interference with the outlet or inlet functionality.

When zone valves are located in the same room as the outlets or inlets they regulate, it could create confusion or complications during operation or maintenance. For instance, if a valve needs to be closed for maintenance, it could disrupt the delivery of medical gases to critical areas or systems. Moreover, having these valves in the same space could lead to potential hazards if there are leaks or operational errors, compromising patient safety.

Therefore, locating zone valves away from the stations they control ensures that the medical gas system operates efficiently, safely, and within regulatory guidelines, promoting ease of operation and maintenance while minimizing risks to both patients and staff.
