Emerson has launched the TESCOM Anderson Greenwood Instrumentation H2 Valve Series for hydrogen applications up to 15,000 pounds-per square-inch (psi) (103.4 megapascal (MPa)). The new solution reliably isolates process pressure in high pressure gas applications such as hydrogen fueling stations and tube trailers, reducing fugitive emissions and improving safety. These maintenance-free valves feature a positive double-block arrangement that protects workers after they isolate process pressures, while their modular design reduces the number of potential leakage points. In addition, the maintenance-free hand-operated DBB valves include a non-adjustable seal that avoids the release of high-pressure liquids or gases into the environment while requiring no packing adjustment over the valve’s lifetime.
