The D/PA(L) type PROTEGO® valve is a highly developed pressure and vacuum relief valve with excellent flow performance. Typically, the valve is installed in the in-breathing and out-breathing lines of tank...
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...
The in-line detonation flame arresters type PROTEGO® DAZ-S are unidirectional flame arresters of the newest generation. The unidirectional (effective on one side) devices protect potentially explosive ...
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...
The PROTEGO® EF/V-IIB3 detonation-safe foot valve protects the suction line in a storage tank. The virtually maintenancefree device is installed at the end of the emptying line within the tank. During suct...
