AVSU AREA VALVES SERVICE UNIT WITH ALARM 27 AVSU AREA VALVES SERVICE UNIT WITH ALARM, SP MODEL The QAG – QAGV area shut-off panel boards are conceived and realized according to the Directive 93/42/EEC and related norm ISO 7396 -1. SISTEMI TECNOLOGIE MEDICALI S.r.l. Their function is to allow, thanks to the built-in ball valves, the exclusion or the passage of the medical gases in a service or area and to define this area from the rest of the network. Downstream each valve for compressed gas it is installed one pressure switch and a specific gas coded emergency terminal unit. For Vacuum network it is installed a vacuum switch only. For each component subject to maintenance / replacement it is provided an anti-return Device in order to allow a quick intervention with a non-stop service. The various types of panel boards are defined by the number of the gas, the presence of the vacuum unit, the presence of the pressure gauge and by the type of panel board mounting of flush or surface ( QAG without vacuum, QAGV with vacuum ). Each QAG – QAGV area shut-off panel board is equipped by cooper pipe ( inlet and output ) to connecting
