Gate valves for aggressive fluids in geothermal power plants

One of the problems faced by geothermal power plant operators is the very short lifetime of valves due to the corrosive and erosive action of the fluid. With standard materials, the average life of a valve installed in geothermal power applications could be five to six months. After this period, valve components like the stem, wedge, and body can begin failing due to the erosive action of the fluid and corrosive effect of the fluid moisture and possible condensation. However, there are new valves that can minimize these effects and extend the life of the installed valves. Using special cladding technology, the valve internals are protected. Tyco Fasani has developed this innovative gate valve design, suitable in applications near the extraction pit where aggressive geothermal fluids are present. This new Fasani design will allow operators to reduce plant shutdowns for the replacement of worn-out components.
