Functional description

The intended use of the Pressure control panel SE45/55/125 is the expansion of a gas from a gas source and the distribution of the gas with adjustable outlet pressure.

To do this, the process gas source is connected to the pressure control panel via the gas connection. In the flow direction of the process gas, the high-pressure process gas shut-off valve (HPI) in connection with the valve combination consisting of purge gas inlet valve (PGI) and high pressure waste gas valve (HPV). Valve HPI is used to shut off the process gas source to the process gas line and for pressure purging in the event of a source change.

The required outlet pressure is set using the pressure regulator. The set outlet pressure can change by varying the inlet pressure or the flow rate.
