LDA

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 Series of Liquid Detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). Arresters was developed for storage tank 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 inside the tank at the end of the line and prevents the combustion from being transferred into the tank 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. ignites. The liquid detonation arresters Detonation flame arrester Flame arrester designed to prevent the transmission of a detonation. function according to the siphon principle in which the liquid product serves as a liquid barrier to 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 up to 1.1 bar / 15.9 psi. This covers all possible operating conditions of empty lines for flammable liquids. The liquid detonation arrester is pressure-resistant up to 10 bar / 145 psi. The device protects against nearly all flammable liquids and is approved for explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. groups IIA to IIB3 (NEC group D to C MESG ≥ 0.65 mm). EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
