In 1903 it was decided to move locations again, this time to a new site where they could build their own factory. In 1904, the new site in Birkby was opened and named The Britannia Works. Britannia Works expanded in 1912, 1920, 1923 and 1926 and by 1938 it covered eighteen acres. In 1912 the company constructed a new steel foundry which was later expanded in 1972.
By 1920 when they became a new Private Company (still keeping the old name) they had a capital of £600,000. Just six years later in 1926 the company became a Public company with a capital of £700,000 and changed their name to Hopkinsons Limited.
In the early 1950s the company expanded into the nuclear industry and furthered this in the 1960s by suppling main steam and safety valves in Britain’s nuclear submarines. By 1976-7 they employed over four thousand people and their sales totalled £32.9 million.
Hopkinson’s expansion was not confined to the Huddersfield, with their success the company expanded across the country and to other countries too. By 1910 there were depots and showrooms in thirty cities across the world including an office in Lille (France), Paris and St Petersburg. In 1973 Hopkinsons was the first British valve maker to be approved for the coveted ‘N-Stamp’ in the U.S.
In 1989 the Weir Group acquired financial control of Hopkinson’s Ltd and in 2002 Hopkinson’s Ltd became a brand name under the Weir Valves & Control division. In 2005 Weir Valves & Controls closed ending 101 years of manufacturing on the Birkby site.
