Medical gas manifold

semi-automatic

Medical Gas Semiautomatic Manifold Deward type to médical applications, first cylinder header change in automatic mode by pressure différence, subséquent header changes in manual mode, ail switchover cicles désignation by main supply cylinder header selector lever, complies with NFPA99 and ASTM B819 (clean for oxygen use). Mounting Plate: • In door use only • Carbon steel sheet 18 gauge made. powder coating finish. • Availabel in stainless steel sheet 18 gauge (upon request). Control System: • PCB electronic system with high bright LEDs visual indicators for manifold operating modes. • Backflow valves (checks) between cylinder headers to pressure diffrerential control. • High pressure 4-20Map transducers to primary and secondary cylinder headers. Visual Signais: • USE-READY-EMPTY condition with high bright LEDs visual indicators for each cylinder header (primary and secondary). Deward Cylinder Minimum Pressure: 230 PSI Bypass System: • 2 Low pressure final line regulators with stainless steel bail valves manual isolation (one regulator in use and the other in backup). Overpressure and Vent Valve: • Low pressure stage relief valve located before manifold outlet to protect the main pipe medical gas source. Communications: • 1 Relay type output connection to médical gas master panel alarm, notify a cylinders header switchover. Emergency Ports: • Located Before end-line regulators and only for low pressure 50-55 PSI. • Coupling with CGA inlet according to the medical gas of the Manifold. Pressure Gauges: High and low pressure analog type.
