Flame arrestor tested according to DIN EN ISO 16852 as a deflagration tube arrestor Deflagration = explosion in which the flame propagates at subsonic speed. The flame arrestor prevents flame propagation to the side to be protected in the event of deflagration of explosive vapor-air or gas-air mix

IFA+EFA valves are currently the most popular model in the Petroster valve offer. They are produced in connection diameters from DN50 to DN200 and various capacity versions. This is a modern design combining a breathing valve with a flame arrester in one device, dedicated to storage and process tank

Flame arresters tested according to DIN EN ISO 16852 as deflagration end devices Deflagration protection Flame arrestor tested as a deflagration end device prevents flame propagation in the event of deflagration of explosive vapor-air or gas-air mixtures from the outside (atmosphere) to the insid

Flame arrestor tested according to DIN EN ISO 16852 as a foot valve (liquid detonation end protection). Detonation = explosion in which the flame propagates at supersonic speed. Deflagration = explosion in which the flame propagates at subsonic speed. Flame arresters tested according to DIN EN IS

Detonation: An explosion in which the flame propagates at supersonic speed. Deflagration = explosion in which the flame propagates at subsonic speed. If explosive gas ignites in a container or pipe, a deflagration (explosion) is triggered. When a flame front travels through a pipe, the flame speed
