    VS/AM 58

    Description

    The direct-operated relief valve VS/AM 58 by Pietro Fiorentini is a safety device which vents gas when the system pressure exceeds the set value due to temporary events, such as expansion due to rise in gas temperature or downstream pressure shocks caused by sudden changes of flow rate.

    Particularly suitable in high-pressure transmission systems and in medium pressure gas distribution networks, this device can be used with natural gas and previously treated, non corrosive gaseous fluids.
