Setball Segmented Ball Valves are cost-competitive general service valves that offer excellent rangeability and high-flow capacity. NAF Setball can be used in a wide variety of applications and meets the highest demands for control accuracy provided by the equal percentage characteristic and the splined connection between shaft and sector.

Features & Benefits
- Segmented ball controls very low flow rates and can open up to large flow rates, resulting in a 300:1 turndown
- Segmented ball provides shearing action as it moves through the seat to cut through debris and provide reliable shutoff
- Low lifecycle and maintenance costs due to the ability to use low operating torque actuators
- Simple rotary action provides options for scotch-yoke and rack-and-pinion actuation, as well as rotary piston cylinder
- Cost-effective control for less severe service applications, without compromising flow characteristic
- The flexible metal seat uses the pressure drops across the seal to enhance its shut-off characteristics in both directions
- Application versatility made possible by specialized options for solutions and stem seals
- Versatile design that combines the best control characteristics of ball and butterfly valves, allowing it to function as a control and shutoff valve
