Wrekin Shell Mouldings (Incorporating William Eagles)

Established in April 1992 and is one of the UK's premier foundries for the production of complex castings using the highly specialised shell moulding process. Shell moulding means: Quality, Accuracy, Consistency, Minimal Finishing, Reduced Metal and Reduced Costs. The customer base consists of sectors such as: water industry, steam mixing valves, fluid handling, bearings & bushes all in copper based alloys.

In 2014 Wrekin Shell Mouldings acquired William Eagles which was established in 1850 and is today one of the UK's foremost manufacturers of firefighting and protection fittings and equipment. Together the two companies trade as Wrekin Shell Moulding Ltd incorporating William Eagles.


‘Dynafluid’ is the brand name founded in Wolverhampton by Meynell Valves, a family Company with its origins in the 18th Century. Dynafluid Ltd was formed in May 1988 when the parent Company was sold to Caradon (now Kohler Mira) and is one of the world’s leading suppliers of steam and water mixing valves with all of the ancillary water guns, hose reels, and complete washdown stations for a wide range of cleaning and process applications.

‘UK Filtration’, a brand which manufactured and supplied a range of strainers/filters to the water and gas industries, was acquired by Dynafluid Ltd in April 2000 and now trades under that name.

Gresswell Valves (incorporating Empire Engineering)

Gresswell Valves was founded in Birmingham in the 1930’s by the Hayes family and built a reputation for a wide range of quality valves and related products. Manufactured in bronze and stainless steel with a wide range of pressure settings Gresswell Valves can be supplied to various specifications to provide safety from potentially lethal over pressure, e.g. boiler systems, pumps, shipping, oil and gas industries and enclosed pressurised systems. In 2002, the company was acquired by the group and relocated to Telford.

‘Empire Engineering’ was another company that manufactured a range of safety relief, pressure relief and vacuum valves in bronze and stainless steel and was acquired by Gresswell Valves in October 2010. Together the two companies trade as Gresswell Valves Ltd incorporating empire engineering. Each one of the above companies compliments the other, thereby attaining the final goal “built in product quality” within a continual improvement framework.
