Zone valve boxes, also known as zone indicator panels, house the zone valves units for each medical gas service. The individual zone valves monitor the pressure for each medical gas and allow the facility quick and easy access to shut off the gas supply during emergency situations. There are single zone valve box units available, or units that can house up to seven zone valves. Each zone valve will be labeled and color coded as per NFPA 99 requirements.
