Automatic changeover valve ,,ACV‘‘ also for hydrogen and oxygen up to 300 bar In cooperation with the company WK Armaturen from Oberursel, we have developed a new fully automatic changeover valve ,,ACV‘‘ made of stainless steel. The ACV ensures a fully automatic changeover with minimal pressure difference between the remaining bottle residual pressure and the output pressure of the cylinder station. It allows maximum emptying of gas cylinder/bottle bundle and is used for non-corrosive gases up to quality 5. 0. In addition to the application for hydrogen and oxygen, the testing and approval of acetylene is sought. The use of contact pressure gauges or sensors with ATEX approval is possible in Ex-Zones.. A modular design allows the use for different inlet pressure ranges: 25 bar for acetylene, 100, 200 and 300 bar for technical gases and high purity gases. With the expansion modules, the system can be extended to 2×2 and 2×3 cylinder or cylinder bundles. The use of a pressure regulator with inlet pressure compensation ensures a constant working pressure. Pros: The use of the new expansion station allows the maximum emptying of the gas cylinder and thus saves money and is environmentally friendly. By using a cylinder station with the ACV, the user only has to remove the empty gas cylinders or replace cylinder bundles with full ones. This task can be done independently by any gas supplier. This eliminates the need to without requiring manual intervention in the pressure control panel. The signal from the pressure gauge of the pressure control panel can be transmitted directly to the gas supplier,
