P/EB-E

The Deflagration-Proof and Endurance-Burning-Proof P/EB-E Type PROTEGO® valve is a highly developed pressure relief valve Soupape de surpression Valve designed to open and relieve excess pressure and to reclose and prevent the further flow of fluid after normal conditions have been restored. for large flows with an integrated Flame Arrester Unit that is specifically designed for use in ethanol production, processing, and storage. It is primarily used as a device Appareil 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. for flame transmission-proof Flame transmission-proof Characteristic of a device to avoid flashback. out-breathing on tanks, containers, and process equipment. The valve offers reliable protection against overpressure Surpression Overpressure refers to an increase in pressure in a system or vessel above the normal operating pressure. and prevents product losses almost up to the set pressure Pression de réponse Set pressure is the gauge pressure at the device inlet at which the relief device is set to start opening under service conditions. , while at the same time protecting against atmospheric deflagration and endurance burning Endurance burning Stabilized burning for an unlimited time. if stabilized burning occurs. The PROTEGO® Flame Arrester Unit is designed to achieve minimum pressure drop with maximum safety. The P/EB-E valve is available for substances of explosion group IIB1 (MESG ≥ 0.85 mm) and provides specific protection against deflagration and endurance burning of alcohol/air mixtures (such as Ethanol/air).

If the set pressure is exceeded, explosive gas/product vapor/air mixtures are released into the atmosphere. If this mixture ignites, the integrated PROTEGO® Flame Arrester Unit (3) prevents flame transmission into the tank. If additional mixture continues to flow and stabilized burning occurs, the integrated Flame Arrester Unit prevents flashback as a result of endurance burning. The valve is protected and also fulfils its function under these severe conditions.
