NAF Ball Sector Valve, Setball

Setball Ball Sector Valve

Brand: Flowserve NAF AB
Add Product to My Catalog

NAF-Setball is a ball sector valve with metal-to-metal or metal-to-PTFE seating. 

The NAF-Setball combines the best control characteristics of the ball valve and the butterfly valve. 

It can be used both as a control valve and as a shutoff valve. It is available as standard in stainless steel. It is also available in other materials, such as, CG8M, Titanium, etc.
Features
  • A one-piece, leak-proof stainless steel body, with face-to-face lengths in according with IEC standards
  • A ball sector with top and bottom bearings for low operating torque, so that low-torque actuators can be used
  • A V-shaped sector that provides accurate control over a wide range, even at low flow rates and if used for viscous media with high concentrations of solid particles
  • A spherical area of the ball sector which, with PTFE-seat gives tight closing. The Stellite seat ring, ensures excellent tightness at all differential pressures. The maximum leakage in the direction of flow is less than 5 x 10-6 of the Kv value in this case. PTFE lined bearings
  • O-ring or graphite packing for the stem gland
  • The standard Stellite seat can easily be converted to PTFE after turning the ball sector by 180 degrees, without the need to dismantle the valve.
