Slam Shut Valve

HBC 975 High-Pressure Slam Shut Valve

The HBC 975 is a safety device that 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 local or remote locations. Designed for high-pressure transmission systems, it is compatible with natural gas and previously treated, non-corrosive gaseous fluids. The device is biomethane compatible and available with specific versions for full hydrogen or NG-H2 blending.

Frequently asked questions

What is the HBC 975 slam shut valve designed for?

The HBC 975 is a top entry slam shut valve for high pressure transmission systems and medium pressure distribution, used at city gates, compressor stations, gas storage sites and power plants. Design pressure is 102 bar with a maximum inlet pressure of 100 bar. Sizes run from DN 100 to DN 300 (4 to 12 inch) with ANSI 150, 300, 600 or PN 16 flanges.

What set ranges and accuracy does the HBC 975 offer?

Both OPSO and UPSO can be set from 0.2 to 90 barg, with accuracy class up to AG 2.5. The valve trips within one second and is reset manually. It includes an internal bypass and a push button for tripping tests, and accepts limit switch and remote tripping options. For lines below 4 inch, choose the SBC 782.

Can Pietro Fiorentini supply the HBC 975 for GCC projects?

Yes. Pietro Fiorentini Saudi Industry in Al Khobar supplies and supports the HBC 975 for city gate and transmission projects in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain and Oman. Send us the line size, flange class and set points to receive a quotation.
