What Is a Two Piece Ball Valve?
A two piece ball valve is a quarter-turn valve with a body construction made of two main sections connected together. Compared with a one piece ball valve, the two piece design provides greater flexibility in size and pressure range while still keeping a compact structure and dependable shut-off performance.
As an experienced two piece ball valve manufacturer, ZONCIC supplies durable valves in stainless steel, carbon steel and special alloy materials. A two piece ball valve is widely used in industrial systems that need reliable sealing, easy operation and more practical maintenance than one piece body designs, while remaining more economical than some three piece configurations.
