Jon Mason of Trouvay & Cauvin explains, “Using only 100% European sourced raw materials, Arflu valves have the significant advantage that all are manufactured in its own factory under the highest quality control and extensive test facilities. The plug valves used in desalination have been designed specifically for this use.”

 

Reverse osmosis forces seawater through a membrane under considerable pressure allowing the pure drinking water through to the other side. In addition to the membrane, control valves are the most critical element. Valve material selection, specification and proven performance are vital given the corrosive conditions. “By understanding the pitting resistance equivalent number (PREN) of the materials, we can guarantee their suitability,”adds Jon Mason.

 

In addition to high-pressure plug valves, Trouvay & Cauvin offers a full range of valves for desalination. Each is designed to international standards with relevant material selection options including Duplex, Super Duplex and Incoloy.

 

Currently Arflu plug valves can be found on many desalination plants including the Shoaiba plant in Saudi Arabia, which with a capacity of 880,000 cubic metres per day is one of the largest in the world.
