Elster Kromschröder valVario® has expanded its family with its latest members, the magnetic relief valves from the VAN series. The field of application includes all gas safety trains for natural gas, LPG (gaseous), biologically produced methane or air, as well as other gas types, if required. Features that stand out are the check indication by a blue LED and the closed position switch (CPS) with visual indicator. In addition, there is an extensive range of variants available for different connection flanges (for pipes up to DN 50) and mains voltages. All the units are EC type-tested and certified. Generally, the magnetic relief valve VAN enables the safe purging of excess or leakage gas. When used in conjunction with a visual discharge unit, it is designed to monitor gas valves for tightness. In the event of leaks, the gas creep is safely discharged via the roof.
