Three Piece Ball Valve

A three-piece ball valve offers several advantages over other valve types due to its unique design and construction. Here's a breakdown of its typical uses:

High-pressure, high-cycle applications: The three-piece design allows for easy disassembly and replacement of worn components

  • Oil and gas pipelines

  • Chemical processing plants

  • Power generation facilities

Applications requiring frequent cleaning or maintenance:  The ability to disassemble the valve simplifies cleaning and maintenance without removing it from the pipeline, minimizing downtime and costs.

Additional Benefits:

  • Full-Port Design: Allows for unrestricted flow with minimal pressure drop, improving efficiency.

  • Bi-Directional Flow : Can handle flow in either direction without affecting performance.

  • Leak-Proof Operation : Tight sealing ensures minimal leakage, even in demanding applications.

  • Durability : Robust construction materials and design contribute to long service life.
