Setball SF

Setball SF

The NAF Setball SF valve is a cost-competitive, compact, rotary control, V-port ball sector valve that offers excellent rangeability and high-flow capacity. In comparison to the NAF Setball, the Setball SF offers a compact design with a short face-to-face.

Cost-effective design; one-piece, leak-proof valve body, with a very compact wafer design

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
