Demand from the Zambian mining industry for valves, and actuator technology manufacturer AR Controls’ product offering, is stable and increasing since Hakainde Hichilema became the seventh President of the country in August last year, says AR Controls CEO Julien van Niekerk. “Demand is relatively stable, owing to our large installed base and the customer satisfaction that we have cultivated over nearly 30 years, facilitating ongoing maintenance, repair and operation (MRO) business.”
