The PROTEGO® DR/EU series of in-line detonation flame arresters represents further development of PROTEGO® flame arrester series DR/ES, which has been successfully used in industry for decades....

The deflagration-proof and endurance burning-proof D-SVL-EB type PROTEGO® valve is a highly developed pressure relief valve for large flows with an integrated flame arrester PROTEGO® EB. It is ...

The compact design of the PROTEGO® FA-G in-line deflagration flame arrester makes it the state-of-the-art technology for installation in pipes with diameters of up to 2”. The devices are installed with minimal dist...

The PROTEGO® FA-G-IIA1-P2.2 in-line deflagration flame arrester was specially developed for bio-, sewage- and landfill-gas applications. The compact design of the PROTEGO® FA-G makes it the sta...

The PROTEGO® BE/HR-400 end-of-line deflagration flame arrester is designed to protect large vessels and process engineering apparatus which are not pressurized. The device provides protection against flame...

The PROTEGO® UB/SF diaphragm valve is the only deflagration-proof and endurance burning-proof valve of its kind in the world. It is a highly developed combined pressure and vacuum valve with dynamic and stat...

PROTEGO® FA-I-V and FA-I-P flame arresters are specifically designed for vacuum pumps, blowers, and compressors. The high flow velocity in the small gaps of these machines can lead to undesirable ignitions...

The PROTEGO® in-line valve DV/ZU is a state-of-the-art pressure and vacuum relief valve with separate flange connections for pressure and vacuum breathing. Typically, the valve is installed in the in-breat...

The SD/BS-H type PROTEGO® valve is a highly developed pressure relief valve with a heating jacket down to the flange. It is primarily used as pressure relief device for vessels and process engineering equi...

The PROTEGO® EB end-of-line deflagration flame arrester provides protection against atmospheric deflagration and long-lasting stabilized flames, called endurance burning. The device is typically installed ...
