Multiple Configuration Options, Specialty Gas Compatible and Ergonomic

Options are good. And so are safety and ergonomics. That's why the VD Series of diaphragm line valves offers low- to high-pressure diaphragm line valves that are fully compatible for all specialty gas applications. With versions available for 50-, 200- and 300-bar inlet working pressure, the VD series valves come with one single design that offers multiple connection options so users can easily configure them to their exact requirements. An ergonomic shut-off handwheel delivers quick actuation, and is marked with clearly visible open/close indicators to help improve safety.
