In the development of the PROTEGO® FA-I in-line deflagration flame arrester, special effort was made to optimize the fluid dynamic flow characteristics. For a given flange connection size of the flame arre...

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...

PROTEGO® lift-actuated vent valves type AL/DK provide automatic venting of floating roof tanks when the floating roof is lowered onto its supports and the tank is either drained or refilled. When the float...

PROTEGO® WV/T change-over valves are mainly used together with other valves or devices (e.g., PROTEGO® flame arresters) on cryogenic storage tanks and on tanks in process plants in the chemical...

The PROTEGO® FA-E-IIA1 series of in-line deflagration flame arresters is designed with an eccentric housing to automatically drain condensate build up in the housing. The PROTEGO® FA-E-IIA1 in-...

The PROTEGO® UB/VF diaphragm valve is a worldwide unique vacuum relief valve combining the function of a dynamic and static flame arrester. It is primarily used as a device for flame transmission-proof in-...

The in-line deflagration flame arresters type PROTEGO® FA-I-PTFE are the latest generation of flame arresters and are distinguished by their unique resistance to adhesive and corrosive media. The use of fl...

The deflagration-proof and endurance burning-proof PV/EBR-E type PROTEGO® valve is a highly developed combined pressure/ vacuum relief valve for high fl ow capacities with an integrated flame arrester that...

The blanketing valve type ZM-R is a highly developed low pressure reducing valve. This valve is typically used to inert or blanket tanks, vessels, or other process systems with nitrogen or other blanketing gases by co...

The PROTEGO® BE-HK-E-IIB3 end-of-line deflagration flame arrester was specifically developed for vessels which are not pressurized and store Ethanol or other alcohols. The combustion of alcohol requires a ...
