External “Pop-Action” Supplementary Pressure Relief Valves for
Small ASME Containers and DOT Cylinders
Designed for use as a supplementary relief valve on small ASME
above ground and underground containers. They may also be used
as a primary or secondary relief device on DOT cylinders, or as
hydrostatic relief valves.
All working components of these relief valves are outside the container
connection, so the valves must be protected from physical damage.

External Hydrostatic Relief Valves
Designed especially for the protection of piping and shut-off valves
where there is a possibility of trapping liquid LP-Gas or anhydrous
ammonia. They may be installed in pipelines and hoses located
between shut-off valves or in the side boss of RegO ® shut-off valves.
