High Pressure Relief Devices (HPRD) An HPRD is a safety device incorporated into an oxygen system, typically in a valve body or other device installed into the cylinder. It is designed to activate in the event of an over-pressure condition which might arise by either over-filling (i.e., filling the cylinder to a pressure in excess of it’s pressure rating), or by being subjected to

Relief valves are another type of pressure relief device. These devices have an inlet static pressure in their design. As the pressure over opening pressure increases a measured and gradual lift operates accordingly. Relief valves are surrounded in spring housing, which makes them ideal for close discharge systems.
