Application
Designed for use as a primary relief valve on ASME above ground and underground containers, bulk plant installations and
 
skid tanks.

The 3131 Series may also be used as a primary or secondary relief valve on DOT cylinders, or as a hydrostatic relief valve.
All working components of these relief valves are outside the container connection, so the valves must be protected from physical damage.

Features
• “Pop-action” design keeps product loss at a minimum.
• Relief valve designed to automatically reseat firmly after
discharge.
• Resilient seat disc provides “bubble-tight” seal.
• 3149 relief valves incorporate integral pipeaway adapter with
break off groove that protects the valve from piping stress
damage.
• Optional pipeaway adapters have grooves that will break off to
protect the relief valve from damage should excess stress be
applied to the piping.
• 3149 relief valves include weep hole deflectors, installed to guard
against flame impingement on adjacent containers.
• Most are ASME rated for use with LP-Gas and anhydrous
ammonia.
