Valves for safer hydrogen fuelling stations
The H2 Valve Series 15,000 psi DBB and hand valves are hand-operated with a maintenance-free design , which minimizes downtime .
As it moves from tank to pump , hydrogen is transferred at pressures of up to 15,000 psi ( 103.4 MPa ). To protect personnel and prevent leaks , it must be effectively controlled and isolated . Emerson ’ s TESCOM™ Anderson Greenwood Instrumentation H2 Valve Series had been designed for hydrogen applications up to 15,000 pounds-persquare-inch ( psi ) / 103.4 megapascal ( MPa ). The Double Block Bleed ( DBB ) 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 .
Clean fuel
Among the cleanest fuels when produced using renewable resources , compressed hydrogen gas is used to power fuel cell electric vehicles ( FCEVs ). In 2021 , 142 new hydrogen refuelling stations began operating , the biggest increase in a single year , raising the total to 685 active stations worldwide . In January 2022 , Global Market Insights Inc . predicted that the FCEV market will exceed USD 15 billion by 2027 . To meet this growth demand , fueling station original equipment manufacturers ( OEMs ) must source reliable , highperformance components to ensure overall equipment effectiveness and ensure station safety . “ Given the pressures that hydrogen is subject to in these applications , it ’ s critical that equipment operates safely and reliably , every time . That ’ s why we ’ re committed to specifically developing components to help our customers effectively store and precisely control compressed hydrogen gas ,” said Rob Lindquist , director of global marketing for TESCOM precision fluid control at Emerson .
Maintenance-free design
The hand-operated , maintenance-free design of the hand valves and double block and bleed valves in the H2 Valve Series minimises maintenance and downtime . With low operating torque and adjustment-free seal technology , these hand valves deliver a low cost of ownership in a compact solution . For OEMs looking to safely minimise risks for operators , the H2 Valve Series provides several safety features . Each valve has a convenient QR code , allowing operators to quickly access the valve ’ s specs during maintenance and installation . The product also ensures that no high-pressure liquid or gas is released during maintenance . The valves are compliant to the ISO 19880-3 hydrogen fueling standard . www . valve-world . net Valve World September 2022
