Pressure Regulator for Bottled Gas DIN EN ISO 2503
Single-Stage Pressure Regulator for Bottled Gas serve to regulate compressed, liquefied and under pressure dissolved gases out of bottles with a maximal pre-pressure of 200 bar up to the desired working pressure, and in fact as independent of pre-pressure or issue quantity fluctuations as possible. Dependency upon pre-pressure is about 1,5% at single-stage pressure regulators, so while deflating the bottle it has to be readjusted from time to time.
Two-Stage Pressure Regulator for Bottled Gas only have a dependency upon pre-pressure of 0,05 %, so readjusting at pre-pressure fluctuations (deflating bottle at compressed gases) is not necessary.
• Single-Stage Pressure Regulator for Bottled Gas Bottle-connection on left side Bottle pre-pressure 300 bar.
• Star-Regulator Bottle-connection on backside – Bottle pre-pressure 200 bar.
Extraction Point Pressure Regulator
Extraction Point Pressure Regulator serve to regulate compressed, liquefied and under pressure dissolved gases from supply grids (ring conducting) with a certain pre-pressure to the desired working pressure, in fact as independent of pre pressure or issue quantity fluctuations as possible. Their composition is analog to the single stage pressure regulators, but because of the relatively low, known pre-pressure, they don’t have a pre-pressure gauge and no safety valve. The high flow rates allow operation of all welding- and cutting torches for acetylene-oxygen, offered by company ewo.
