    \n

    Application<\/h2>\n

    Main gas train to EN 746-2. This is a part of the gas distribution system of the industrial thermoprocessing equipment (IThE), e.g. for downstream single burner systems.<\/p>\n<\/div>\n

    \n

    Function<\/h2>\n

    If the main shut-off valve (010) is open, the pressure and quantity required for the IThE are controlled by the gas pressure regulator (050).Any dirt in the gas or pipe system will be removed by the filter (020) first.<\/p>\n

    The automatic shut-off valves (090) are part of the protective system, as are the low-pressure cut-off (070), the high gas pressure protection device (080) and the valve proving system (110). These compulsory safety devices are actuated separately by the process control system. In the case of insufficient or excessively high gas flow, the process control system will receive a signal and shut off the gas supply safely by closing both valves (090). Before each commissioning or after switching off the system, the valve proving system (110) checks the functioning of these valves.
    \nThe quantity of gas consumed can be read off the flow meter (060). The inlet and outlet pressure will be displayed on the pressure gauges (030\/040).<\/p>\n<\/div>\n<\/div>\n<\/div>\n
