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

SFA is a series of breathing valves with a three-way design, dedicated to specialized applications and installations operating in closed vapor circulation. Unlike EFA and RFA, SFA valves have separated overpressure and underpressure discs, which allows for an individually selected ratio of the inhal

RFA is a series of breathing valves without a flame arrester, available in sizes from DN50 to DN300 and dedicated to installations requiring high inhalation capacity. They have discs integrated into one unit, as in the case of EFA, but their disc proportions have been reversed to obtain the highest

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

Flame arrestor tested according to DIN EN ISO 16852 as a liquid detonation end-of-line device. Detonation = explosion in which the flame propagates at supersonic speed. Deflagration = explosion in which the flame propagates at subsonic speed. The flame arrestor prevents flame propagation during d

Pressure/vacuum valve and deflagration end-of-life protection
 Pressure/vacuum valve tested as a flame arrestor according to DIN EN ISO 16852. Ventilation lines on storage tanks prevent negative and positive pressure during filling, emptying, cleaning, heating, cooling or inerting of the container

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
