Control Valves for Corrosives
30 October 2008
Where process applications require control valves which are able to withstand the effects of highly corrosive media Badger RC250 barstock valves are the ideal choice.
The Badger range of valves is available in the UK through liquids handling specialists Pump Engineering, and includes a wide range of options, such as the RC250 model.
The valves are available in a range of materials including, stainless steel, Hastelloy, Monel and titanium and will handle flows from 100 lit/hour up to 8000 lit/hour, at pressures up to 9 Bar. RC250 valves feature; Linear or equal % trims, Hastelloy C and Tantalum trims, Kynar trim Cv’s from 6.0 to 0.05 and metallic trim CV’s from 6.0 to 0.0000018. The valve is available in sizes ¼”, ½”, ¾” and 1” with NPT or wafer style connections and a choice of Teflon CV rings or REK packing is available. Control options include pneumatic and electric actuators.
The RC250 (807) barstock model is also available in PVDF and will therefore withstand a wide range of corrosive media occurring in water treatment, chemical feed, pH control, semiconductor and pulp & paper applications. These type of applications could involve aggressive fluids such as; sodium hypochlorite, chlorine dioxide, sulphuric acid, sodium chlorate, ammonium fluoride and hydrochloric acid, all of which can be safely handled by the RC250 PVDF valve.
