End of line valves
Flame arresters designed to prevent the transmission of the flame from the outside environment into the piping system or tank. They are always located at the end of the piping system or on the tank lid. From a design point of view, end of the line valves can be divided into end of line breather vent without a flame arrester and end of line breather vent with flame arrester element. According to the method of protection, end of line valves can be divided into overpressure, vacuum or breather vents. To select the right end of the line valve for your application, please contact our technical or sales department.
