What is a chip-type stainless steel valve?

A chip-type stainless steel valve is a type of valve composed of multiple valve bodies connected by bolts. It is primarily made of stainless steel (such as 304 or 316L), offering corrosion resistance and excellent sealing, making it particularly suitable for applications requiring frequent opening and closing or demanding high media cleanliness. It mainly comes in three structures: one-piece, two-piece, and three-piece, each with its own characteristics.

What are the characteristics of stainless steel ball valves?
