The lubrication of a ball valve requires a different practice to the lubrication of either a gate valve or plug valve.
Field experience has shown that some greases and sealants may cause severe problems with the seat and seal arrangement if used regularly during preventative maintenance. If a non-leaking ball valve is lubricated with too solid of a grease, the floating, spring loaded seats can become stuck within their seat pockets. When the ball floats due to a pressure differential across the valve, the seals cannot track the ball and leakage can occur.
"We were introduced to a new product, Claretech BVL and the consistency was slightly softer than Valve Lubricant 601TM. Many of the operators felt this was important to ensure that the spring loaded seats function correctly to achieve a seal."
