VALVES: Pressure Relief & Relief Valve Manifolds
External "Pop-Action" Supplementary Pressure Relief Valves for Small ASME Containers and DOT Cylinders 3127 and 3129 Series
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.
