New valves for hydrogen-fueling stations
The Tescom Anderson Greenwood Instrumentation H2 Valve Series (photo) is suitable for hydrogen applications up to 15,000 psi (103.4 MPa). The new valve reliably isolates process pressure in high-pressure gas applications, such as H2 fueling stations and tube trailers, reducing fugitive emissions and improving safety. The double-block-and-bleed valve’s positive double block arrangement provides two layers of positive shutoff that shield maintenance staff from high pressure during instrument maintenance. Its modular design reduces the number of potential leakage points, and the reinforced sealing technology reduces the risk of fuel entering the atmosphere through the valve stem. The hand-operated, maintenance-free design of the hand valves and double block and bleed valves in the H2 Valve Series minimizes maintenance and downtime. — Emerson, St. Louis, Mo.
