Medical Gas Zone Valve Box

Reliable shut-off valves for medical gas pipeline safety and maintenance

The Silbermann Zone Valve Box supports patient safety by controlling medical gas supplies to designated areas, including operating rooms, intensive care units, and patient wards. Its shut-off valves let teams isolate specific zones during a leak, emergency, or planned maintenance without disrupting medical gas delivery to other areas of the facility.

The Zone Valve box serves gases such as:

oxygen
medical air
nitrous oxide
vacuum.

Each service has its own shut-off valve, allowing staff to isolate one medical gas line without interrupting the others. Includes color-coded labels.

Available with a pull-out removable window or an aluminium door.
