The multi-purpose applicable single-seat control valves made by KIESELMANN are available both in linear and equal-percentage version. The fittings are based upon the hygienic and proven concept of the KIESELMANN KI-DS valves. Their control accuracy and cavitation resistance were optimized in simulations and tests. Owing to a large range of nominal widths and Cv values as well as different connection variants, there is the suitable component for every application. The advantageous removable seat concept allows an easy adaptation to changing process conditions. Offering nominal widths of PN 10 as well as different metallic and elastomer sealing concepts, these valves allow the user a safe and exact process control and sealing
