Lined Ball Valve Application

I. Overview: Pipelines are the optimal method for transporting fluids. Compared to soft-seal ball valves,Lined Ball Valve offer advantages such as reduced fluid resistance, quick and easy opening and closing, excellent sealing, long life, high reliability, and ease of integration with electric and pneumatic devices. They can also adapt to a wider range of temperatures and fluid media, making them widely used in pipeline transportation. The ball and seat of a hard-seal ball valve are both made of metal. This metal-to-metal sealing pair is commonly referred to as a hard seal.
II. Applications: Hard-seal ball valves are primarily used in pipelines in the petroleum, natural gas, and chemical industries. Compared to soft-seal ball valves, hard-seal ball valves are primarily used in the following two operating conditions: ① High-temperature applications (graphite packing seal); ② Normal-temperature applications with powdered or granular media in the pipeline (O-ring seal).
