HVAC Controls > Asco Solenoid Valves
In 1888 ASCO started out manufacturing elevator, compressor and generator controls and in 1910 became the first company to develop and manufacture a new electrically operated control device known as the solenoid valve. ASCO continued its development activity in these product areas and today manufactures products that are designed to control the flow of air, gas, water, oil and steam - practically every kind of liquid or gaseous substance.
In 1985 ASCO is acquired by Emerson Electric Co., a fortune 100 company located in St Louis, Missouri. Three years later Emerson buys Joucomatic, Europe's leading name in pneumatic valves, and combines it into the ASCO family. In 2008 ASCO and Numatics, companies of Emerson Industrial Automation, merged operations in North America to form ASCO Numatics -- a unified company that offers comprehensive flow control and pneumatics solutions for a wide range of industry-focused applications.
