## Summary

The contracting authority, Sellafield Limited based in Warrington, has completed a procurement process entitled "Process Water Header Isolation Valves" within the goods category. The procurement was carried out through a direct method below the threshold, thereby not involving competition. This process led to an award to Flow Control Solutions Ltd on 5th September 2025. The scope involves the supply and installation of four process water header isolation valves, spool pieces, and spare repair kits at a contract value of £41,094.23, effective from 8th September 2025 to 24th November 2025. This project addresses operational efficiency concerns due to incorrect current valve installations.

This tender presents substantial opportunities for businesses within the flow control and valve manufacturing industries, particularly those with expertise in designing and supplying customised valve solutions. Companies capable of delivering high-pressure testing certifications and those adept at collaborative design with industrial plants would find this type of procurement particularly suitable. Participating in such contracts can significantly enhance business growth by aligning with public authorities to solve critical operational issues, thereby establishing long-term relationships with a major buyer like Sellafield Limited.

## Notice

Flow control to quote and supply X4 process water header isolation valves two different sizes, X2 spool pieces that fit in-between the pipework and the valve again two different sizes, and X2 spare repair kits for the valves. Included in the price is also a pressure test certificate which is needed to prove its up to its safety function. We have had to have design involvement as the current valves that are installed are the wrong type of valve (Globe valve hard seats) and are passing and causing issues along with operator burden. These Worcester valves are a must for plant to work more efficiently.
