THE FIRST STAGE PANEL BOARD APR 180 WITH AUTOMATIC SWITCH – OVER SYSTEM for central stations in cylinders is conceived and manufactured according with MDD 93/42 EEC and subsequent amendments and harmonized standards ISO EN 7396-1, EN 10524-2, EN 737-3 as well as according with HTM 02-01.
The panel boards are realized with a varnished stainless steel frame integrating:
. High pressure shut-off valves, double rod type , in order to facilitate opening and closing
operations.
. Pressure gauge with down – stream alarm contact set at 20/30 bar according with the supplied medical gas and signaling of empty manifold with a red LED
. High load pressure reducers realized with hot printed brass body
. All manometers are equipped with a safety glass
. All high pressure reducers are equipped with a PFTE membrane
. Safety valves directly mounted on the reducers
. Low pressure valves realized in nikel plated brass with stainless steel ball
. System of automatic fl ow switch-ovwe by means of a nylon pneumatic variation system
. Sensor indicating “ working manifold “ by means of a green LED
. Terminal switch for wiring distance alarm signaling system
The main structure integrates 2 black bakelite handles for easy installation or transport
The switch-over between the two supplying sources is automatically realized by means of a
pneumatic switch-over device placed after the two pressure reducers.
This situation allows the passage from one source to the other source by means of the
pneumatic piston sliding in/out according with the variation of the reducer output pressure.
