Pietro Fiorentini HBC 975 Slam Shut Valve Technical Brochure
The Pietro Fiorentini HBC 975 is a safety device designed to quickly interrupt gas flow when pressure reaches a set value. It is primarily used in high-pressure transmission systems and medium-pressure gas distribution networks, suitable for natural gas, oil, hydrogen, and biomethane applications.
Key features include a response time within 1 second, a top-entry design for easy maintenance without removing the valve body from the pipework, and the ability to retrofit existing pressure regulators. The valve can be tripped automatically, locally via a button, or remotely via system monitoring.
