Engine Protection
HOERBIGER supplies Explosion Relief valves to protect combustion engines from devastating effects of oil- mist or gas explosions. Together with core engine manufacturers, we have developed appropriate safety systems that are still setting standards today.
Independent of the industry, whether on Marine, Power Generation or Land-based energy applications, we are prepared to offer an appropriate, certified solution.
Regardless of the engine type, the hazard of a potential oil mist explosion in the crankcase is always present. Therefore, proper protection is mandatory for both, people and equipment.
In the event of an explosion, the venting device opens by lifting the valve plate, and directs the vented explosion through the flame arrester, preventing flames from being expelled to the surrounding areas. Both the EVO & EVX are equipped with a conical spring, immediately after the pressure event, the valve plate closes and resets airtight.
HOERBIGER Crankcase Relief valves are a reusable, flameless venting device, protecting personnel and equipment. For 4-stroke engines the HOERBIGER valve series “EVO” and for 2-stroke engines the HOERBIGER valve series “EVX” set the standards.
Engines which burn low flash point fuels, have in case of back- or misfire a potential explosion risk in the inlet and exhaust manifolds.
HOERBIGER Manifold Relief valves are a reusable, flameless venting device, protecting personnel and equipment. The HOERBIGER valve series “EVT” protect both, the engine inlet manifold and the engine exhaust manifold in case of back- or mis-fire.
