AR Controls’ valves for demanding applications

17 July 2017

AR Controls has successfully supplied and maintained large installed bases of DeZurik KSV severe-service knife gate valves on the Zambian Copper Belt in demanding tailings applications.

The most popular valves supplied by the company are cast stainless steel, urethane-lined and severe-service knife gate valves, as well as high-performance and concentric butterfly valves, general and severe-service ball valves, and non-return valves.

All the internals of this valve, apart from the urethane lining, as well as the upper works and actuation, are standardised from the stalwart DeZurik KGC Cast Stainless knife gate valve. It can handle pressures of up to 17.2 bar, and has the same face-to-face dimensions as KGC valves.

The company offers a refurbishing service for its OEM valves that have reached their end of life, restoring them to their original standard for further use at customers’ operations. All valves refurbished by AR Controls have an 18-month warranty.
