DR/SV

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® DR/SV 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. Series ideally combines the function of a detonation arrester Detonation flame arrester 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 Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). 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 Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. 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 Operating pressure 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.
