Gas relief valve EVT series

high-pressurefire protectionflame arrestor

The Explosion Relief Valve EVT is a reusable, flameless venting device, whichis designed for the protection of personnel and equipment in case of gasexplosions, or engine “mis-fire” or “back-fire.” In the event of an explosion,the venting device opens by lifting the valve plate, and directs the ventedexplosion through the flame arrester, preventing flames from being expelled tothe surrounding areas. The relief valve type EVT is equipped with disc springs,immediately after the pressure event, the valve plate closes and resets. Features • ATEX and IACS certification • Optimum protection for personnel and equipment • Flameless explosion pressure relief • No shut-down required after an explosion/back-fire • Flexibility due to variable installation position • All valves are functionally tested when built Application Explosions can occur in the intake or exhaust manifolds of combustionengines when gaseous fuels are used. Gaseous fuels are a continualpresence in the intake manifold(s), while the exhaust manifolds maycontain unburnt gaseous fuel in both dual-fuel and gas engines, especiallyduring start-up or fuel-mapping stages. The techniques of mis-fireor back-fire prevention and the use of relief valves is a proven way tomitigate equipment damage from over-pressure and flame, and preventinjury to personnel.
