Each recessed zone valve box consists of the following components: A steel valve box which can house one to seven shut-off ball valves with tube extensions, an aluminum frame and a pull-out removable window. Gauge options are 100 psi, 300 psi or 30 inHg. Terminal strips are provided with the box. The sensors and DISS fittings are gas specific, and provided with the alarm.
The valve box is constructed of 18 gauge steel, complete with a baked white enamel finish. Affixed to the opposite sides of the box are two adjustable steel brackets for the purpose of mounting the box to the structural support. The steel brackets accommodate various finished wall thicknesses between 3/8″ (9.5 mm) and 1-3/16″ (30 mm) and are field adjustable.
The frame assembly is constructed of anodized aluminum and mounted to the back box assembly by standard #6 * 3/8″ tapping screws provided. The removable front consists of an opaque window with a pullout ring pre-mounted to the center of the window.
Access to the zone shut-off valves is done by merely pulling the ring assembly to remove the window from the frame. The window can be reinstalled without the use of tools only after the valve handles have been returned to the open position. The window is marked to prohibit unauthorized persons from tampering with the valves with the following silk-screen caution: “MEDICAL GAS CONTROL VALVES. CLOSE ONLY IN EMERGENCY”
