The Explosion Relief Valve EVO is a reusable, flameless venting device that is designed for the protection of personnel and equipment in case of oil mist or gas explosions in the crankcase of gas, diesel, or dual-fuel engines. In the event of an explosion, the venting device opens by lifting the valve plate and directing the vented explosion through the flame arrester, preventing flames from being expelled to the surrounding areas. The relief valve type EVO is equipped with a conical spring; the valve plate closes and resets immediately after the pressure event.
Features
- ATEX and IACS certification
- Optimum protection for personnel and equipment
- Flameless explosion pressure relief
- No shut-down required after an explosion/back-fire Application
- Flexibility due to variable installation position
- All valves are functionally tested when built
Explosions can occur in the crankcase of combustion engines, large compressors, gearboxes, and transmissions. Internal components of these devices cause the oil to form a cloud or mist throughout the confined spaces. In the case of gas-burning or dual-fuel engines, gas can also escape into the crankcase or other confined spaces of these applications, creating a dangerous environment for explosions. Relief valves are a proven way to mitigate equipment damage from overpressure and flame and prevent injury to personnel.
