The Georg Fischer Type 523 Ball Valve is ideal solution where precise flow control is needed. It has a special V-notch ball and operates with a 180º turn versus a 90º turn most ball valves have. The Type 523 has an integrated scale to indicate degrees of opening and provides a very linear flow curve. Polypropylene, PVDF, and PVC are the available materials (CPVC and ABS on request).
