Neles Series E2/E6 Ceramic Ball Control Valve
Brand: ValmetMetso's Neles Series E ceramic ball valve is one of the most erosion resistant control valves available today. It is used in abrasive applications such as lime mud, metal slurries, titanium dioxide, and cement production, where even stellited surfaces do not last.
A new generation of ceramic material, magnesia partially stabilized zirconia (Mg-PSZ), completely lines the Series E flow path.
The properties of Mg-PSZ are superior to those of the more common ceramics found in other valves, making it suitable for a wide range of severe service industrial applications.
Designed with a wafer style body rated for ASME Class 150 or 300 / PN 10 to 40 applications, the E2 is available in sizes DN 25 to 100 / 1" to 4".
The flanged E6 is available in sizes DN 25 to 200 / 1" to 8" with ASME Class 150 or 300 / PN 10 to 40 rating.
FeaturesResists mechanical and thermal shock
- A transformation toughening process gives Mg-PSZ high strength and exceptional fracture toughness, making it extremely resistant to mechanical shock.
- Superior thermal shock resistance capabilities allow for the use of Mg-PSZ without the need for careful warming and cooling of the piping system. This maintains ceramic integrity and prevents cracking.
- Mg-PSZ is an ideal replacement for ordinary, low-strength, brittle ceramics.
Total erosion resistance
- A completely ceramic flow path without metal parts provides maximum erosion resistance.
Rigid single-piece body
- A rigid stainless steel body withstands pressure loads and pipeline forces to protect the ceramic material.
Increased stability and control
- The ball-to-stem connection is a strong, backlash-free blade joint design.
- The blade joint design eliminates lost angular motion between the ball and stem and provides better control.
Live loaded PTFE packing
- Minimizes fugitive emissions.
- Eliminates the need for frequent packing adjustment.
High strength
- The 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.
Exceptional toughness
- Due to special transformation toughening features the ceramic material is fracture resistant and not subject to brittleness as traditional ceramics.
