HANGONG (GC) designed a continuous gas supply device of inert or active gas according to the use of industrial gases in various gas consuming equipment and most laboratory equipment (analytical instruments, chromatograph or mass spectrometer), so as to realize the continuous, stable and safe use of industrial gases.
The modular design of HANGONG gas pressure switching device, including: manual gas pressure device, semi-automatic switching device, automatic switching device, etc., can be used for a variety of flammable gas control.
The module includes a connectable extension port, which is easy to increase the gas source and provides more choices for field gas supply. The gas supply can be specially extended, extended or manufactured according to the different operating conditions required by the site.
Gas application module device is simple and beautiful. The installation is convenient and the operation is strong.

Specification size

Manual gas pressure switching device
Inlet pressure 300bar, both sides of the air inlet are equipped with check valve, filter and purge valve, and equipped with safety leakage protection pressure relief valve and other accessories.
Semi automatic gas pressure switching device
For the double source design, high pressure gas can be reduced to 10~15bar in the 300bar side, in the work of the state, the other side is in the standby state, can automatically switch to the empty bottles from the side of the bottle device comprises a valve, globe valve, filters, valves, purge valve and pipeline switching valve and pressure pipeline.
Full automatic gas pressure switching device
The automatic switching device is suitable for high end modern experiments, factories and special dangerous environment applications, using solenoid valve to maximize gas savings. The gas remote monitoring is carried out by the electric contact pressure gauge and signal device, and the gas leakage alarm is installed. The matching devices include pressure reducing valve, solenoid valve, PLC valve, check valve, control unit and signal detection equipment.
