Request a quoteAn automatic changeover manifold with manual reset, the Rotarex CEN switchover board, for the high flow supply of non-corrosive industrial gases, sized for plasma, TIG and MIG cutting and welding: 70 to 180 Nm3/h of nitrogen on the 200 bar version and 50 to 130 on the 300 bar version, with outlet versions of 10, 16, 30 and 50 bar. Balanced valve regulation holds the outlet steady as inlet pressure changes, so no second regulator is needed downstream, and up to six cylinders connect without extensions when the purge line is not used. Chrome plated or raw brass, about 13.8 kg, with a non-whipping inlet filter, an optional quarter turn outlet valve and alarm box connection through contact gauges. Carbon dioxide, acetylene and propane versions exist.
