Great valve reliability

In the oil and gas industry, the reliability of valves is never a secondary concern.
Valves are the gatekeepers of process integrity, responsible for controlling flow, isolating equipment and protecting both people and infrastructure in environments that often push materials to their absolute limits.
Severe service applications — those involving high temperatures, abrasive fluids, corrosive chemicals, or rapid cycling — present particular challenges for valve seat materials.
For decades, engineers relied on polymers such as PTFE, PEEK, or UHMWPE. These materials offered low friction and chemical resistance, but these have struggled to survive when exposed to extreme heat, pressure, or erosive solids.
In recent years, carbon graphite has emerged as a transformative option for ball valve seats in severe service.
Unlike polymers, carbon graphite is a structural material with intrinsic properties that align remarkably well with the demands of the oil and gas sector.
Its stability at high temperatures, self-lubricating nature, chemical resilience and resistance to wear have made it increasingly attractive for operators who cannot afford...
