scaling and ultimately cause complete valve failure. Another challenge for the geothermal business can be project duration: the traditional deployment of geothermal power plants can take years, from project start to having power online. These projects require large investments, and, in these kinds of huge projects, reliable and experienced partners are often welcome.
Safe, reliable, and energy efficient
With reliable, high-quality valves, geothermal power plants can produce renewable energy efficiently and safely at a low cost and low environmental impact. The availability of the geothermal plant is crucial, which is why durable valves requiring minimal maintenance are preferred. Our proven valve solutions are an ideal fit for the geothermal industry where the natural variation of fluid conditions can be very demanding. Valmet has one of the industry’ s widest product scope with an extensive pressure rating for the wellhead-steam lines to the main steam distribution system within a geothermal plant. We have notable experience in sizing and selecting theright valves for geothermal service. In addition, if maintenance or expert help is needed, we also support our clients with comprehensive life-cycle services. One service that has been well received is our resident engineer service. This is when we assign a dedicated local service technician to the factory. In a case in Turkey for example, a geothermal power production facility contacted us to provide immediate service support to help solve their valve problems and

minimise production losses. With several on-site visits per month, the geothermal facility reduced production losses and was ultimately able to define and prevent potential future problems.
The right valves for geothermal plants
Some of the options are our Neles and Jamesbury valve solutions, which ensure efficient and reliable operation in geothermal power plants. The heavy-duty Neles™ Finetrol™ eccentric rotary plug valve is for separator level control( LCV). Neles™ metal-seated butterfly valves have demonstrated long, maintenance-free service in geothermal plants worldwide. Their eccentric plug or triple eccentric disc design, combined with hard-coated metal seats, allows continuous operation even under heavy scaling. On the turbine side, particularly in binary cycle( ORC) plants, customers

rely on high-performance, soft-seated Jamesbury™ Wafer-Sphere™ valves. These examples highlight how valves are critical in geothermal energy. Our broad range of control valves, backed by industry experience, supports safety and environmental compliance. Our technical expertise also offers solutions for the requirements of new geothermal technologies such as SHR and SCGT. As an established name in mining, metals and steel processingaround the world Valmet also offers wide portfolio of flow control solutions for lithium production from brine sources.
Bright future for clean energy
As the technologies surrounding geothermalenergy continue to develop, we are hopeful for a future where this clean source of energy plays an increasingly major role in society.
