The slam shut valve HBC 975 by Pietro Fiorentini is a safety device which quickly intercepts gas flow when the pressure it is monitoring reaches a pre-set limit due to any anomaly in the system, or when required by the operator at the installation point or from a remote point.

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

HBC 975 is Hydrogen Ready for NG-H₂ blending.
