Safe systems in practice PROTEGO® devices are used in a wide range of industrial applications. A safe process requires reliable protection for every conceivable operating parameter. Practical examples show how systmes can be made safe and how PROTEGO®

Protection of flares Equipping elevated flares or ground flares with DA-SB detonation flame arresters. Equipping the emergency vent stack with VD/SV-HRL deflagration-proof endurance burning-proof pressure and vacuum relief valve. Gasholders with DR/SBW

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 Flame Arresters (or ‘flame arrestors’) are designed to allow the flow of gases, liquids, etc. and to prevent flame transmission. PROTEGO® Flame Arresters are composed of individual FLAMEFILTER® (flame arrester discs),

PROTEGO® Breather Valves In closed containers or tanks containing liquids, effectively managing pressure is crucial. To ensure secure operations, it is vital to have a dependable mechanism for releasing accumulated pressure and compensating for vacuum conditions.
