Is Dewrance Obsolete? – The short answer is no!

Many companies believe that the Dewrance range of valves is obsolete and no longer available. We would like to take this opportunity to confirm that such a claim is wholly without truth, and that the Dewrance range of valves is still in manufacture and is available.

There has, however, been some rationalisation and reduction to the Dewrance range, especially in low pressure general service valves and smaller sizes below 6”. This was conducted to focus the Dewrance brand into the Power generation marketplace at a level where the product range was most technically suited and commercially accepted.

In the event that a Dewrance product is no longer available we will be happy to assist in locating an alternate product.

The history of Dewrance

John DewranceThe DEWRANCE name owes its origin to John Dewrance, a pioneer of steam locomotive development.

He was responsible for the construction of George Stephenson’s locomotive “The Rocket”, assisting at the Rainhill trials in 1820. The success of “The Rocket” during these trials resulted in its use on the Liverpool & Manchester Railway.

The founders pioneer efforts in connection with therailways naturally influenced his engineering activities and a business was established in South London in 1844. John Dewrance & Co., was soon to become known as an innovative manufacturer of products for steam application.

Sir John Dewrance took over control of his father’s business in 1879. Under his guidance, the pioneering work of his father continued. In 1882 he married Isabella Trevithick, granddaughter of Richard Trevithick, one of the leading early railway pioneers.

He became a director and Chairman of Babcock & Wilcox Ltd in 1899 a position he held until one year before his death in 1937. At this time, the company became a wholly owned subsidiary of Babcock & Wilcox eventually moving to Skelmersdale in 1965.

Today, the Dewrance brand is a owned by Emerson.
