In general, the ball valve stem is not set on the upper and lower seals, so no special maintenance, but long time use of the stem due to wear or aging, may leak in the stem. If the stem has an injection port, add sealing grease to the injection port to prevent leakage; If the stem is of other construction, fill the packing or press the packing gland according to the structure of the stem to eliminate the leakage fault. It is important to note that if sealing grease injection is required, it should be done slowly with a manual grease gun.
