International. 15,000 pound-per-square-inch purge valves and double-block manuals offer redundant high-pressure protection and superior sealing technology to prevent leakage.
Emerson's new solution, the new Emerson solution, the H2 series of TESCOM Anderson Greenwood Instrumentation valves reliably isolates process pressure in high-pressure gas applications such as hydrogen refueling stations and tubular trailers, reducing fugitive emissions and improving safety.
"As it moves from tank to pump, hydrogen is transferred at pressures up to 15,000 psi (103.4 MPa). To protect personnel and prevent leaks, it must be effectively controlled and isolated," the company said in a statement.
It argues that the double positive block arrangement of the double block purge valve (DBB) provides two layers of positive closure that protect maintenance personnel 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," he says.
On the other hand, it highlights that compressed hydrogen gas is one of the cleanest fuels when produced with renewable resources and used to power fuel cell electric vehicles (FCEV).
According to the same company, in 2021 142 new hydrogen supply stations began operating, the largest increase in a single year, increasing the total to 685 active stations worldwide.
In January 2022, Global Market Insights Inc. predicted that the FCEV market will exceed $15 billion by 2027. "To meet this demand for growth, service station original equipment manufacturers (OEMs) must source reliable, high-performance components to ensure overall asset efficiency and station safety," Emerson said.
"Because of the pressures hydrogen is subjected to in these applications, it is critical that the equipment operates safely and reliably at all times. That's why we're committed to specifically developing components that help our customers effectively store and precisely control compressed hydrogen gas," said Rob Lindquist, Director of Global Marketing for Precision Fluid Control at Emerson.
Lindquist explains that the design of the manual valves and the double locking and purging valves of the H2 valve series, manually controlled and maintenance-free, minimizes this and downtime.
"With low operating torque and no-fit sealing technology, these manual valves offer a low cost of ownership in a compact solution," he says.
Finally, the multinational guarantees that the product does not release any liquid or gas at high pressure during maintenance. The valves comply with the ISO 19880-3 hydrogen supply standard.
