What is the lip seal for a ball valve?
Lip seals are defined as sealing devices designed to prevent leakage and minimize friction between moving parts, such as valve stems in engines, by balancing film thickness and lubrication efficiency. They typically feature sharp or stepped lips to maintain low leakage rates under varying pressure conditions.

Can you overheat a ball valve?
Overheating Ball Valve
Excessive heat can cause the valve's materials to expand. This causes leaks, deformation, or even complete valve failure. Overheating might occur due to factors like high fluid temperatures, inadequate cooling mechanisms, or improper valve selection.
