Stage II Reduction Groups

The reducers are designed to transform the line pressure at 8 bar (or 10 bar) to end-use pressure at 3.5 bar (or 8 bar), with a flow rate from 35 mc/h up to 50 mc/h inducing a low pressure drop . The 2nd stage reducers are mounted in semi-recessed bottom with door, lock with Sicure Lock system and gauge reading window. The reduction unit is equipped with Afnor, UNI or NIST sockets. There is a backstop under the pressure gauges to remove a damaged or uncalibrated gauge and automatically prevent gas leakage. Reduction units are supplied with pressure transducer or pressure switches.
