No. | Component description | Standards and Docuthek |
---|---|---|
010 | Manual isolating valve, e.g. manual valve AKT | |
020 | Filter, e.g. gas filter GFK
Our tip: at maximum flow rate, filters should show a pressure loss of no more than 10 mbar. |
|
030-040 | Pressure gauge, e.g. pressure gauge with capsule element KFM or pressure gauge with Bourdon tube RFM with pressure gauge valve DH or MH | |
050 | Low-pressure cut-off, e.g. pressure switch for gas DG
The min. pressure switch setpoints to be adjusted depend on the installation location and the process conditions. Our tip: pressure switches should be installed preferably with horizontal or vertical diaphragm. Ensure that no dirt or moisture can penetrate the open ventilation ports. |
|
060 | High gas pressure protection, e.g. pressure switch for gas DG
The max. pressure switch setpoints to be adjusted depend on the installation location and the process conditions. Our tip: pressure switches should be installed preferably with horizontal or vertical diaphragm. Ensure that no dirt or moisture can penetrate the open ventilation ports. |

070 | Automatic shut-off valve, e.g. solenoid valves for gas VAS
|
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 single burner systems.
Function
If the main shut-off valve (010) is open, the gas flows through the filter (020). Any dirt in the gas or pipe system will be retained.
The automatic shut-off valves (070) are part of the protective system, as are the low-pressure cut-off (050) and the high gas pressure protection device (060). 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 (070).
The existing gas pressure will be displayed on the pressure gauges (030/040).
