ASCO was founded in 1888 as a manufacturer of elevator, compressor, and generator controls. In 1910, the company invented a new electrically operated control device known as the solenoid valve. ASCO's heritage of innovation resulted in an extensive line of products that ranged from two position on/off valves to entire flow control systems designed to provide thousands of customer-specific solutions.
