History

Canadian John Leslie made a steam powered snowplow for railroads based on the patent assigned to him by Orange Jull.[3] By 1905, Leslie was operating a foundry in Lyndhurst, New Jersey and making steam pressure valves and regulators. During World War I and World War II, Leslie supplied military and merchant ships with steam control equipment.[4]

In 1968, after the company had expanded its product line to include industries and utilities, Leslie built a plant in Parsippany, New Jersey.[4]

Leslie moved to Tampa and was purchased in 1990 by Watts Industries, Inc. Leslie bought K&M Valve Company in 1995.[4]

Watts started Circor International in 1999 when it spun off valve and control businesses relating to oil and gas.[5]

On November 16, 2021, HornBlasters announced that they had acquired the Prestigious Air Whistles Division of Circor Leslie Controls, the oldest locomotive horn manufacturer in the United States. As a result, Circor Leslie Controls' horns, including its Supertyfon RS horn, will be sold by HornBlasters starting in 2021.[6][7]
