What is a Stainless Steel Ball Valve?

A Stainless Steel Ball Valve is a type of quarter-turn shut-off valve made from SS304, SS316, or special alloys that resist rust, corrosion, and chemical attack. These valves use a rotating ball to start or stop flow and are known for:

  • High strength
  • Smooth operation
  • Long lifespan
  • Compatibility with aggressive media
