Setball SF Ball Sector Valve

Brand: Flowserve NAF AB

The NAF Setball SF from Flowserve is a highly versatile and cost-effective solution to a range of general services as well as erosive applications such as fibers and slurries. 

A V-port ball sector valve designed primarily for modulating control applications, the Setball SF can also be used effectively for shut-off service. 

It combines a compact design with excellent equal percentage flow characteristics and high flow capacity
Features
  • A ball sector with a V-port resulting in excellent control characteristic in combination with high flow capacity and high rangeability
  • A very compact wafer design for weight reduction and cost savings
  • A one-piece, leak-proof stainless steel valve body to minimize leakage paths
  • Enhanced product integrity through a spring loaded stem seal packing that provides a long, maintenance free and safe operation
  • Dual low friction bearings and a specially designed seat, resulting in a smooth operation and making it possible to use a small actuator
