Cornick and Morris delivers 90% cost saving for leading manufacturer

An industry leading manufacturer of valves used in the Gas, Water and Utilities industries approached Cornick and Morris for help with the development of a new range of Pressure Independent Control Valves. The customer wanted to use a polymer based construction, as opposed to machined brass which is traditionally used, in an effort to reduce costs.

Cornick and Morris' engineers put forward a product proposal using alternative materials and processes which they were confident would meet the overall project objectives, whilst maintaining the tight tolerances achieved through machined brass.

Using a process above the "glass transition temperature", Cornick and Morris was able to manufacture a set of valve cartridges with crystalline structure which maintained tolerances of less than 0.05mm using Polyphenylene Sulphide; the finished product range maintains all of the technical desirables of the initial design, whilst delivering a 90% cost saving over traditional materials and manufacturing processes.
