Geothermal & Power Generation

Geothermal power plants are sustainable, non-polluting and reliable, but they can be really challenging endeavors with steam temperatures exceeding 570°F (300°C). Valves installed in Geothermal plants have to face flashed steam, hot water and geothermal brine where abrasive and highly corrosive chemicals and minerals could erode and damage sealing surfaces, impairing valve performance. ERREESSE strong expertise and know-how on materials and new technologies results in a large range of ball valves with specific designs, constructions and selected materials, to address the most challenging situations and corrosion issues on Geothermal applications.
