When the city of New York calls and asks for your help, you listen. This happened in 2009, because the Larner-Johnson valves that helped supply water to 10 million people needed an upgrade. My name’s John, and I’m the Technical Director at Blackhall Engineering: the ultimate valvologist behind this 100-year project. It may surprise you to hear an American city came to Brighouse for help, but it shouldn’t. After all, the original Larner-Johnson valves far surpassed expectations, so here at Blackhall we provided the obvious solution - But not before overcoming the ultimate challenge of combining our prestigious technical expertise with today’s most innovative technology.
Developing these bespoke valves that will last another 100 years, we play an important role in New York’s daily water supply. I guess you’d like to know how we did it and what we did, so let me explain more in the video below..
Used for Inline Pressure or Flow control Applications. The valve can also be used for Free Discharge Control at pressure above that of the Fixed Cone valve and offers fine control. For full specifications and details…

Submerged Discharge Valve
When low discharge noise is a requirement and space is at a premium, our Submerged Discharge Valve is an ideal fit. Because discharge occurs under water and into a Stilling Well, this valve lowers noise and takes up minimum space. For full specifications and details…
"The installation was very professional, alongside the commissioning and testing. The valves have worked perfectly since installation. Please express my gratitude to all concerned on a job well done"

Unearthing the 100 year project
An incredible project like this takes an entire team of experts working together. I'm proud to play a role, not just within Blackhall, but alongside the likes of JAMES BLACKHALL whose dedication and hard work in the beginning of the project paved the way for everything else.
MIKE McCARTHY continues to build and nurture our relationships in America, ensuring the likes of TED DALE on the design team keep busy with new innovations. This is where we continue to surprise our clients like New York, providing solutions to problems they didn’t think they could overcome. And with guys like TOMMY SCANLON on the factory floor ensuring the assembly team works in unison, we're in great hands. This only scratches the surface, because everyone in Blackhall's family plays an important role in a project like this. I’m proud to be part of it, and I know my colleagues are, too.
