Metso Automation E Series Ceramic Ball Valve - One of the Most Erosion Resistant Control Valves Available.NORTHBOROUGH, Mass. -- Metso Automation's Neles E Series ceramic-lined ball valve ball valve n. A valve regulated by the position of a free-floating ball that moves in response to fluid or mechanical pressure. , using a new generation of ceramic material, provides users with the most erosion resistant control valve currently available. Completely lining the flow path, the magnesia Magnesia, ancient cities, Lydia Magnesia (măgnē`zhə), two ancient cities of Lydia, W Asia Minor (now W Turkey). They were colonies of the Magnetes, a tribe of E Thessaly. partially stabilized zirconia (Mg-PSZ) is superior to the more common ceramics found in other valves, making it suitable for a wide range of severe service industrial applications. The Neles E Series valve is ideal for abrasive applications such as lime mud control, kaolin kaolin (kā`əlĭn): see china clay. , china-clay control, calcium carbonate calcium carbonate, CaCO3, white chemical compound that is the most common nonsiliceous mineral. It occurs in two crystal forms: calcite, which is hexagonal, and aragonite, which is rhombohedral. handling, gypsum gypsum (jĭp`səm), mineral composed of calcium sulfate (calcium, sulfur, and oxygen) with two molecules of water, CaSO4·2H2O. It is the most common sulfate mineral, occurring in many places in a variety of forms. handling, cement production, metal slurries, catalyst regeneration, desulphurization units and more. Features of the Neles E Series ceramic-lined valve with Mg-PSZ include: --Resistant to mechanical and thermal shock - maintaining ceramic integrity and preventing cracking, making it an ideal replacement for ordinary low strength, brittle ceramics. --Total erosion resistance - a completely ceramic lined flow path without metal parts provides maximum erosion resistance. --Rigid stainless steel stainless steel: see steel. stainless steel Any of a family of alloy steels usually containing 10–30% chromium. The presence of chromium, together with low carbon content, gives remarkable resistance to corrosion and heat. single piece body - withstands pressure loads and pipeline forces to protect the ceramic material. --Increased stability and control - the ball to stem connection is a strong and backlash free blade joint design, eliminating lost rotation between the ball and stem, which improves control stability. --Live loaded, double set of PTFE PTFE polytetrafluoroethylene. V-ring packing - minimizes fugitive emissions and eliminates the need for packing adjustment. --High tensile strength - 450 MPa exceeds the strength of other ceramics commonly used in industrial practice to such a degree that this material can be considered close to steel. --Good thermal shock resistance - standard material has temperature shock resistance of +710 degrees F. Higher values are available upon request. --Exceptional toughness - due to special transformation toughening features the ceramic material is fracture resistant and not subject to brittleness as traditional ceramics. Designed with a wafer style body rated for ASME ASME - American Society of Mechanical Engineers Class 150 or 300 applications, the E2 is available in sizes 1" - 4". The E6 is available in sizes 1"-6" with ASME Class 150 or 300 rating. When traditional metal seated control valves are failing prematurely due to erosion, it makes good financial sense to upgrade to the Neles brand E-Series ceramic ball valve, as down time and maintenance costs should be considered when calculating the total cost of ownership. With the E Series, two, three and four times the service life is not uncommon in many severe abrasive applications. For more information, contact Metso Automation 1-508-852-0200.
