Richter Chemie-Technik GmbH is introducing a new size control ball for its KNR and KNAR control ball valve series.
Increasing production quantities increasingly require larger diameters of pipelines and therefore larger valves. In so-called world-scale facilities, everything is optimized to the maximum possible capacity for the best economic results. With our new PFA-lined control valves KNR/F DN200 (8“), the largest control ball in the world, we respond to these changing customer requirements. We have succeeded in ensuring a very stable mass flow with low pressure losses. The geometric contour also ensures low turbulence throughout the flow range. The control characteristics and true equal percentage curve is valid at various flow rates up to a kv value of 1000 m3/h (CV = 1156 gpm).
Richter’s proven KNR design with play-free one-piece ball shaft, leak-free labyrinth seal and the maintenance-free Envipack stem sealing ensures a long lifetime and maximum safety.
