In order to ensure a sufficient degree of safety & reliability of gas supply, gas pressure reducing station (PRS) are used.
It is recommended to use Twin / Dual stream Pressure Reducing Station, so that incase of working line failure / under maintenance the stand by line can take over the supply function.
We can supply Pressure Reducing Station having active monitor pressure regulator configuration & metering device also.
Gas Trains For Pressure Reducing System :
A gas train consists of Filter, Slam-shut off valve, pressure regulator, safety relief valve & flame arrestor. Filter helps to remove the dust / dirt particles in the gas which may damage the regulator parts. The slam shut off valve normally remains open. Incase the outlet pressure of the regulator exceeds the permissible limits, the slam shut off valve senses it through the impulse line & instantly shuts off the supply to the downstream system. The safety relief valve is provided for additional safety. It is to be set at higher pressure than the slam shut off valve pressure so that the safety relief valve will operate only when slam shut off valve fails to operate. The outlet of the safety relief valve is vented well above the roof.
