Salt Lake City-based Mooney Controls was founded in 1984 by Dick Mooney, a mechanical engineer with over 25 years experience in industrial controls and the natural gas industry. The Flowgrid® Regulator he developed is a patented, pilot-operated pressure regulating valve for both gases and liquids, and is now known for its unparalleled high performance, ease of maintenance, low minimum differential, reliability and versatility. The Flowgrid® is available in sizes 1" through 12".

In 1990 Mooney Controls developed and patented the Series 20 Pilot Regulator for accurate pressure control of the Flowgrid® and other pilot-operated regulators. Its removable body insert, which contains the inner-valve assembly, is now an industry standard for performance and ease of maintenance.

In 2000 Dresser Mooney Controls introduced another innovation: the FlowMax® Regulator. The FlowMax is a pilot-operated regulator that offers bubble-tight shutoff at all pressure drops and full capacity at very low-pressure differentials. The complete line is now available in 2", 3", 4" and 6" sizes.

Dresser is a worldwide leader in the design, manufacture and marketing of highly engineered equipment and services sold primarily to customers in the flow control, measurement power segments of the energy industry.
