The PROTEGO® LDA-WF(W) series of liquid detonation flame arresters was developed for storage container filling lines that are not continuously filled with product and sometimes contain a combustible mixtur...
The PM/(D)S pilot-operated PROTEGO® diaphragm valve is a highly developed valve for pressure and vacuum relief. It is primarily used as a device for out-breathing in tanks, containers, and process equipmen...
The PROTEGO® FA-I-FC flame arrester units are components installed on or within equipment (e.g. blowers) and have to be tested and approved with this equipment for the respective operating conditions of us...
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® DR/SV flame arrester series ideally combines the function of a detonation arrester with the advantages of a shut-off valve. In case of ignition, the fire can be stabilized within the flame ar...
Universal Floating Suction Units FSU are designed to ensure that product in a storage tank is drawn off just below the surface of the liquid where it is cleanest, preventing the suction point being at the bottom of th...
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...
EV/VS and EV/VD flame arrester units provide manufacturers of vacuum pumps, blowers and compressors with a cost-effective protection for their machines. The high flow velocities in the small gaps of these machines can...
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 PROTEGO® roof drain valves D/SR or D/SR-W have the function of an inlet cup, which collects the rainwater from the floating roof through the scissor pipes of a PROTEGO® floating roof draina...
