Glass Bulb Pressure Relief Devices
Superior performance, higher reliability, and greater safety with glass-blub PRD technology
NorAm Valves designs and manufactures premier pressure relief devices (PRD) for the gas transport industry. The thermally-activated PRD protects against failure of a pressurized cylinder by quickly releasing the contained gas. Replacing the less reliable eutectic metal or fusible metal orifice barriers with glass bulb technology. NorAm’s patented PRD is the most reliable and safest option in the marketplace today.
The PRD complies with the Compressed Gas Association’s Pressure Relief Device Standards Part 1 CGA S-1.1 – 2022 types CG-9 (natural gas) and CG-10 (Hydrogen) for use on cylinders up to 7540 psi (520 bar).
