LDA-W

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® LDA-W Liquid Detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). 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. was developed for storage container filling lines that are not continuously filled with product Product Includes equipment, protective systems, devices, components and combinations of these. and sometimes contain a combustible mixture. 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. is installed outside the container in the filling line. If the explosive atmosphere Explosive atmosphere A mixture of air and flammable substance in the form of gases, vapors, mists or dusts under atmospheric conditions in which, after ignition, spreads to the entire unburned mixture. is ignited, the device prevents the combustion from transferring into the tank. The PROTEGO® LDA-W Series of Liquid Detonation Flame Arresters function according to the siphon principle in which the liquid product serves as a barrier against flame propagation.

The application range for the device is a product vapor / air mixture temperature of up to +60°C / 140°F and an absolute pressure of up to 1.1 bar / 15.9 psi. This covers all possible operating conditions of empty lines for flammable liquids. The liquid detonation arrester Detonation flame arrester Flame arrester designed to prevent the transmission of a detonation. is designed for pressures of up to 10 bar / 145 psi, resists explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. pressure, and provides protection for almost all flammable liquids. The device is approved for explosion groups IIA to IIB3 (NEC group D to C MESG ≥ 0.65 mm).
