DR/SV

The PROTEGO® DR/SV Flame Arrester Series ideally combines the function of a detonation arrester Arrête-flammes antidétonation Flame arrester designed to prevent the transmission of a detonation. with the advantages of a Shut-Off Valve. In case of ignition, the fire can be stabilized within the Flame Arrester when the flammable gas continues to flow. Inside the detonation arrester, is a valve (1) that closes in case of fire, stops the additional supply of fuel and extinguishes the flames.

Once a detonation enters the Flame Arrester, energy is absorbed from the detonation shock wave by the central plate disc (2) before the flame is extinguished in the narrow gaps of the two FLAMEFILTER® discs (3). This device can be used for fluids of explosion group IIA (NEC group D). The In-Line Detonation Flame Arresters are unidirectional and equipped with a threaded connection. The thread can be executed to international standards. The standard design can be used up to an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of +60°C / 140°F and an (absolute) operating pressure Pression de service Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to 1.1 bar / 15,9 psi. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
