Richter KNR 200

Richter, a leader in PFA lined pump and valve solutions, is introducing a new size control ball for its KNR and KNAR control ball valve series.

Increasing production quantities require larger diameters of pipelines and thus also larger valves. In today’s world-scale plants, everything is optimised to the maximum possible capacity for best economic results. Richer anticipated these changing requirements with the launch of the world’s largest PFA-lined control ball for the KNR/F DN200and the KNAR/F 8”valves. The optimisation of flow behaviour supported by CFD (Computational Fluid Dynamics) has allowed us to ensure a stable maximal flow with minimal pressure losses. The geometric shape ensures low turbulence throughout the flow range. The control characteristics and true equal percentage curve at various flow rates up to a kv of 1000m³/h (CV = 1156gpm)

Richter’s gas tight KNR/F 200 excels in:

  • Universal chemical resistant PFA lining ≥6mm thickness
  • Permeation and vacuum resistant construction
  • Higher efficiency due to better control behaviour, especially in the lower range
  • Lower operating costs by increased capacity – kv = 1000m³/h (CV = 1156gpm)

Richter’s proven KNR design with play-free one-piece ball shaft, leak free labyrinth seal and maintenance-free ENVPACK stem sealing ensures a long lifetime and maximum safety. See more… /products/brand/richter
