IAG nG MSJ gas line switches are impressive for their extremely compact design, lasting, complete seal tightness and maintenance-friendliness.

IAG nG gas line switches are especially impressive because of their compactness and long life even under heavy usage conditions. As with every IAG nG device, special attention is paid to careful gas flow with minimal internal volume and no stub lines or undercutting, as well as uniform heating with ample performance for heating up quickly. The MSJs have an in-built heat regulator for internal heating. Control of the compressed-air balanced valve is bit parallel with 24V control voltage. The maximum line diameter for gas inlets for the MSJ12 is 35mm.

The MSJ 2,4 and 8 are backflushable. The MSJ 2 can be equipped with 2 extra heating circuits for oncoming heated lines. Maximum inlet pressure for all MSJ is 3 bar. All MSJ are available in a high pressure version for max. 6 bar inlet pressure. If an MSJ is connected to an IAG nG measuring unit, control, parameterisation and monito- ring can be carried out via the measuring unit display.
