View Petroster Sp. j. on TEKEN44IFA+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 tanks with flammable media requiring balanced aeration and venting parameters. Their main tasks are to protect pipelines and tanks against fire entering them, automatically regulate the pressure inside the tanks and prevent spontaneous emission of vapors into the atmosphere. They have been tested and approved as protection against deflagration conditions for gas mixtures, vapors and mists of substances classified into explosion groups IIA, IIB1 and IIB (including group IIB3).
