Metso has been supplying automated on/off and control valve solutions, smart instrumentation, configuration/diagnostics/optimisation and predictive maintenance tools for both the more traditional power plant designs and the rapidly growing newer technology sectors during the last decades. These include conventional thermal power plant boiler & steam turbine, simple cycle gas turbine, cogeneration plant, waste and other bioenergy plants and circulating fluidised bed boilers. Challenges such as noise and cavitation control, emissions control and critical service are areas in which our expertise enables improved performance. Our customers include the foremost suppliers of high quality products and engineering services to the global power industry such as Foster Wheeler Energy, General Electric, Siemens & Siemens Westinghouse, Alstom, Babcock Borsig, Ansaldo and ABB.
For demanding services like feed water control & MP de-aerator level, the Neles top-entry T-series rugged MP & HP control valve design allows unsurpassed control stability, wide rangeability and tight shut-off. Noise and cavitation is under control with optional Q-Trim noise attenuation. Neles Finetrol and Segment valves are excellent for accuracy and wide rangeability to increase control under all LP & MP process conditions with optional Q-Trim noise attenuation in applications such as water treatment, fuel control and LP & MP steam. In applications like LP turbine steam induction, cooling air and blow off, Neldisc® triple eccentric metal seat valves ensure superior sealing under difficult conditions, such as high thermal cycling. Options include S-Disc flow-balancing noise trim & ZeroLeakTM design. Rugged MBV & X series full or reduced bore ball valve with high temperature, tight shutoff capabilities and optional Q-Ball noise attenuation and anti-cavitation trim are ideal for different on/off purposes.
