BE/HR-400

The Pressure/vacuum relief valve Pressure/vacuum relief valve is an umbrella term that includes pressure or vacuum relief valve as well as pressure and vacuum relief valve. PROTEGO® BE/HR-400 End-of-Line Deflagration Flame Arrester Deflagration flame arrester Flame arrester designed to prevent the transmission of a deflagration. It can be an end-of-line flame arrester or an in-line flame arrester. is designed to protect large vessels and process engineering apparatus which are not pressurized. The device Device A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. provides protection against flame transmission through atmospheric deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). and stabilized flames which can burn for very long time on the flame arrester Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. element surface, so called endurance burning Endurance burning Stabilized burning for an unlimited time. . Main application area is on in- and out-breathing and vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration from propagating into the vessel Vessel Container or structural envelope in which materials are processed, treated or stored. or plant.

The FLAMEFILTER® discs are arranged concentrically and are manufactured in a patented process. The FLAMEFILTER® casing has integrated cooling channels to allow heat to be transferred away from the center of the device. The PROTEGO® BE/HR-400 End-of-Line Deflagration Flame Arrester is available for substances from explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group IIA (NEC group D). The standard design can be used for operating temperatures up to +60°C / 140°F. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
