They assumed control of the company after their father Carl Mosack retired as president in 2001. The Mosack family has led the privately-held company for three generations. Nearly all Apollo® valves are produced in U.S. facilities that are second to none in the industry, including ISO-registered, state-of-the-art foundries and manufacturing facilities in Pageland and Conway, S.C. The company's headquarters is located in Matthews, N.C. By focusing on problem-solving innovations, U.S.-made quality and the best delivery and fill rates in the industry, Apollo Valves will continue to thrive.
