Isolation Valve FAQs
Isolation Valve Case Studies
Urgent Isolation Valves for Airport Flood Management
In 2020 after intense rainfall, Dubai International Airport’s stormwater management system was overwhelmed, leading to submerged runways and hundreds of flights being delayed or cancelled.
T-T Flow supplied multiple specialist isolation valves to the repair and upgrade effort, including butterfly valves and wedge gate valves for reliable sealing and flood management.
Securing Water Supply with Butterfly Isolation Valves
A distribution reservoir in Market Drayton found the security of its water supply was at risk due to poor sealing from highly corroded legacy isolation valves.
The site's primary contractor came to T-T Flow needing a fast solution. Our team specified and supplied centric butterfly valves for immediate installation on the site without the need for costly amendments to existing infrastructure.
Penstock Valves for Complex Underwater Installation
Keepers of a boating lake in Greater Manchester came to T-T's valve experts in need of a robust replacement for their failing penstock valve.
Extensive corrosion meant that the valve was no longer isolating properly and making it difficult to manage lake water levels. The penstock was needed on a fast turnaround in order to coincide with the arrival of specialist underwater contractors to complete the installation.
