This valve is installed in a water pipeline, for America’s largest inland metropolitan area, Dallas – Fort Worth Metroplex (DFW) province which is the economic and cultural hub of North & Central Texas.

This High Pressure 108 inch Parallel Faced Metal Seated Gate Valve is designed and manufactured by Blackhall Engineering Valves. The specifications of these magnificent valves were stated by some of the USA’s top consulting engineering firms like AECOM, CDM Smith, Black & Veatch and Freese & Nichols.

The success of any highly engineered product depends not only on the design, but equally on the manufacturing and assembly processes involved. Advanced Casting Simulation Programme was employed to optimise the casting process to ensure the castings manufactured were free from any residual stresses that could potentially develop during the solidification of metal.

Transporting such a huge valve across America was very challenging due to the size and load restrictions on many of the roads and bridges. Many of the jobsites are very remote with poor access. The Engineering team had to design a valve that could be built and tested within the factory then dis-assembled, shipped and re-assembled on the jobsite. Manipulation and realignment of very large components being key to all of these operations.
