From the outset, we were very pleased with the help given by Blackhall during the design, construction and subsequent testing/commissioning of the valves and would not hesitate in contacting them again should a similar project arise.

The installation was very professional, alongside the commissioning and testing. The valves have worked perfectly since the installation.
