Additionally , the need for precise flow control in semiconductor manufacturing has led to advancements in valve actuation and control systems , benefiting other industries that use oxygen and clean gas systems .
High temperature applications
While current industry standards cover applications from cryogenic temperatures up to 200 ° C , there ’ s a growing need for solutions beyond this range .
Vahe adds , “ We ’ re seeing demand for valves that can operate safely at temperatures above 200 ° C in oxygen service . It ’ s a challenging area , but one where we ’ re actively developing solutions .” Velan offers specialised high temperature oxygen applications above 200 ° C ( 400 ° F ), extending beyond the typical range covered by standard industry guidelines .
The growing importance of hydrogen
As more industries look to use hydrogen , valve makers face new challenges . “ Hydrogen introduces risks such as material embrittlement ,” Doug explains . He adds , “ The industry is developing specialised sealing solutions and adapting cleanliness standards for these applications to minimise risk .” Hydrogen valves must meet varying requirements . Fuel cell vehicles need ultra-pure hydrogen , while industrial uses often require valves that withstand higher pressures and temperatures . Vahe adds , “ Preventing leaks is crucial . Hydrogen can escape through tiny gaps that would contain other gases , therefore creating better seals and more precise components is necessary .”
OXYGEN VALVES
A key to safety in oxygen applications
Doug concludes with a cautionary note about the risks of treating oxygen service valves as standard components : “ It ’ s not advisable to simply request an oxygenclean valve from a local distributor who might claim , ‘ We cleaned it in-house .’ This approach can lead to significant problems and safety risks .” As the industry adapts to new challenges , including higher operating temperatures and the increasing use of hydrogen , valve manufacturers must continually refine their processes . This includes staying current with the latest safety standards , investing in advanced cleaning facilities and providing comprehensive training for all staff involved in valve production . For those specifying or using valves in oxygen and clean gas applications , it ’ s crucial to work with manufacturers who can demonstrate a thorough understanding of these specialised requirements . By doing so , users can ensure they ’ re getting components that not only meet current standards but are also prepared for future developments in this critical field .
