Description
The RegO 3127 Series is an external pressure relief valve designed for LPG and related pressure-system applications.
RegO specifies the 3127 Series for use as a supplementary relief valve on small ASME above-ground and underground containers. Depending on the specific model, it may also be used as a primary or secondary relief device on DOT cylinders or as a hydrostatic relief valve.
The 3127 Series is particularly relevant where piping or shut-off valves can trap liquid LPG between closed valves. In such applications, the valve provides hydrostatic pressure relief protection for the affected section of the system.
