It has been one hundred years since Canadian born John Leslie advertised his first major product, a steam powered snowplow for railroad locomotives. By 1905 The Leslie Company was operating a foundry, machine shop and small office in Lyndhurst, New Jersey, and building a reputation for producing reliable steam pressure valves and regulators. The company was a major supplier of steam control equipment for military and merchant ships during both World Wars and has continued as a supplier of military/commercial marine service products. Leslie's product line grew over the years to incorporate equipment for industrial and utility customers, and in 1968 the company moved into a larger plant in Parsippany, New Jersey.
In Parsippany, Leslie built on decades of experience manufacturing high quality valves for military and industrial markets to solidify its reputation as a premium quality manufacturer, with products such as the venerable "Super G" Series regulators and the Class DLO control valve line.
After moving our headquarters to a newly built 150,000 sq. ft. facility in Tampa, Florida, Leslie broadened its scope to encompass a comprehensive array of products for total fluid management of steam and other fluids. In 1990, Watts Industries, Inc., one of the world's largest independent valve manufacturers, purchased Leslie Controls, Inc.
1994 marked the introduction of Aeroflow, one of the most innovative and diverse family of control valves in the world. The Watts acquisition provides a broader scope of fluid control products distributed throughout the global marketplace. Watts and its subsidiaries design, manufacture and sell an extensive line of valves to the plumbing and heating, municipal water, power, chemical, petrochemical, industrial, and oil and gas markets. Our 1995 aquisition of the K&M Valve Company added the widely recognized K-Max Rotary, GTB Top & Bottom Guided, GTW Three Way, and Synflow Sweep Angle control valve lines to our Process Chemical and Oil & Gas Industry offerings. With 250 employees, Leslie Controls, Inc., has grown to serve power generation, oil and gas, petrochemical, chemical process, HVAC, food processing, commercial marine, and military marine markets through a network of over 100 manufacturer's representatives worldwide.
