SBC 187


The slam shut valve SBC 187 by Pietro Fiorentini is a safety device which immediately intercepts gas flow when the pressure it is monitoring reaches a pre-set limit due to any anomaly in the system, or when enabled manually.

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

SBC 187 is Hydrogen Ready for NG-H2 blending.
