Protection of floating-roof storage tanks
Floating-roof storage tank with
floating-roof drainage system SE/K, roof valve D/SR, stem-actuated valve AL/DK with deflagration flame arresters EB, rim vent P/EB.
Protection of fixed-roof storage tanks
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.
The deflagration proof gauging pipes with integrated flame arresters type PROTEGO® PU are used for explosion-proof gauging of tank contents. The gauging pipes of type PROTEGO® PU consist...
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
The VN-VU type PROTEGO® valve is a highly developed vacuum relief valve with excellent flow performance. It is primarily used as a device for relieving vacuum in tanks, containers, and process engineering ...
The VN-VL-L type PROTEGO® valve is a highly developed vacuum relief valve with excellent flow performance. It is primarily used as a device for relieving vacuum in tanks, containers, and process engineerin...
Protection of roofed storage tanks for ethanol and other alcohols
Deflagration-proof Vacuum Relief Valve PROTEGO® SV/E Detonation Flame Arrester PROTEGO® DR/ES or PROTEGO® DR/ES-V with integrated Check Valve The venting line is designed to provide
The deflagration proof and endurance burning proof PROTEGO® DE-S type device is a state of the art high velocity vent valve working on the principle of a dynamic flame arrester. It is primarily used as a d...
