Valves For Seawater Application required in United Kingdom

I have one project in middle east which they need valves for sea water application!!!
Do u have any agent in middle east?
And if you dont have; can i know what is the brand of your company or if you can lead me for a company which is specialised in sea water valves!!!!
Coz the project which iam working with.. need to specify these valves,
so the consultant of the project will approve the materials throw the presentation of your company.
