World's Largest Valves designed to last for 100 years
Weighing at 117 tons and standing a majestic 40 feet tall, Blackhall's Zero-Leakage Metal Seated Parallel Faced Gate Valve has been designed to last for 100 years. The DN2800 / 108 inch dia Gate valves are designed and manufactured for America's 1st platinum rated water pipeline project IPL (Integrated Pipeline). The project will drastically boost the water supply to Dallas-Fort Worth Metroplex by 1.59 billion Litres (350 Million Gallons) per day by 2060.
Along with the wealth of experience, heritage and technical knowledge, it was Blackhall's proven track record of manufacturing 100 year asset life valves for water industry that matched perfectly with Tarrant Regional Water District's 100 year sustainability promise on the IPL project.
The gate valves which are the World's Largest Valves of their kind in terms of weight and size, successfully passed all hydraulic tests (Shell Strength at 375psig and Seating Capability tested at 250 psig)
