Our Technology

A leader in safety, NorAm Valves manufactures top of the line Cylinder End Plugs that are the most reliable and safest option in the marketplace today. The thermally activated Cylinder End Plug protects against failure of a pressurized cylinder by quickly releasing the contained gas. This low-profile Cylinder End Plug offers a tamper proof PRD and threading for compression fittings to direct flow of pressure. This aluminum cylinder plug is ideal for large capacity, high pressure cylinders, and when coupled with the NorAm Eagle ¼-turn valve, it completes the gas storage and delivery package.

The Cylinder End Plug is certified to 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). (CG-10 cert expected to be completed in August)

Key Benefits
Utilizing the low-profile design, NorAm’s Cylinder End Plug places the glass bulb within the plug section that sits inside the cylinder. Unlike most standard PRDs where the bulb is at the front of the plug, this system eliminates the possibility of dislodging the glass bulb during installation and ensures maximum reliability in case of a failure.
The glass-bulb orifice barrier is activated by temperature (102°C), not pressure. It has a faster reaction time than traditional thermal relief devices. Even if a cylinder is less than full, the device can be activated in a fire.
BayoTech’s Cylinder End Plug has a flow rate that exceeds any other product currently available. With glass bulb technology, there is no danger of residual metal blocking the venting process. Emergency venting can occur efficiently and rapidly, thereby greatly improving safety.
