External “Pop-Action” Supplementary Pressure Relief Valves for Small ASME Containers and DOT Cylinders
Info
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.
