Protection of Processing Facilities Tank farms for flammable liquids with pressure and vacuum relief diaphragm valve UB/SF, connection to gas vent header system with detonation flame arrester DR/ES-V or DR/ES and pressure or vacuum relief valve DZ/T.

Pressure and Vacuum Relief Valves for Cryogenic Storage Tanks Decades of experience in manufacturing pilot-operated pressure/vacuum relief valves, our expertise in computer-optimized design, and our extensive test facilities form the basis for the development of

Working principle of Flame Arresters A Flame Arrester is designed to allow the safe flow of gases and liquids while preventing flame transmission. Flame Arresters are composed of spirally wound metal bands with precisely reproducible flame-quenching gaps.

Diaphragm Valves PROTEGO® Diaphragm Valves function as pressure vacuum relief valves. The flexible diaphragm allows them to work as a dynamic flame arrester which provides endurance burning protection. For additional safety, these devices are equipped with a
