Our tip: at maximum flow rate, filters should show a pressure loss of no more than 10 mbar.Application
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 multiple burner systems.
Function
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.
The low-pressure cut-off (070) and the high gas pressure protection device (080) are part of the protective system. 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 two valves fitted in series. These valves can be part of the downstream burner system.
The 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).
