Pressure Relief Valve deflagration- and endurance burning-proof
Subsonic combustion that propagates through a flammable mixture by heat transfer.
Typical in gas/vapor cloud ignition (not a detonation).
Generates rapid pressure rise, but not shock-wave level.
It maintains pressure relief function during and after exposure to a deflagration event.
It does not rupture, seize, or lose set pressure integrity due to flame or pressure wave.
Internal components resist thermal distortion and flame impingement.
