Large Valves for Severe Service
for refining, chemical / petrochemical, oil & gas, and slurry transport processes
Prior to 1999, MOGAS defined large valves as 10 inch and above. By 2007, 15% of MOGAS valves being manufactured were 14 inch and larger. Since then, MOGAS has redefined large valves as 24 to 40 inch (previously 10 to 18 inch). Over 15 years, from 2007 to 2021, manufacturing these larger valves sizes have increased by more than 6%.
These large valves, typically 24 to 36 inch, are all metal-seated ball valves for severe service applications.
