QSLM Dual inlet decompression unit with automatic change-over system FEATURES

Transcription

1 Strada dei Boschi, Villasanta (MB) Italia tel QSLM 2000 Dual inlet decompression unit with automatic change-over system FEATURES It allows the use of two cylinders or packs of cylinder; when one source of pressure drops below the threshold value, the second gas supply automatically sets in. Turning the lever, the side with priority supply will be set. During first cylinder discharge, outlet pressure drops from maximum change-over pressure to the minimum; turning the lever the outlet pressure rises to the maximum supplied by the second full cylinder. Inlet pressure up to 220 bar (3190 psi) for standard version. Outlet pressure up to 15 bar (218 psi), is controlled by a diaphragm; instead, greater outlet pressures are controlled by a piston. The decompression unit is suitable for all industrial applications such as welding, cutting and laser systems. Available the ATEX version branded II2GDcIICX. Applicable in potentially explosive areas: 1, 21, 2, 22 (not applicable in mines and zone 0). The product complies with the directive 97/23/CE (PED)
