Application scenarios
Rotary control of highly abrasive slurries in pulp and paper processes
For regulating abrasive slurry lines containing solid particles in pulp and paper plants. The E series features a full ceramic flow path (ceramic-lined flow path and trim) for highly erosive rotary control service, helping extend valve service intervals and reduce maintenance requirements.
Rotary control of highly erosive media in petrochemical and refining processes
For regulating process media lines where erosion risks exist in petrochemical and refining plants. The E series full ceramic flow path is suited to highly erosive rotary control applications, supporting longer plant run times, reduced maintenance, and low-emission operation.
Selection points
Full ceramic flow path and trim
The full ceramic flow path consists of a ceramic-lined flow path and ceramic trim with no wear-prone metal parts, suitable for highly abrasive media and erosive service, helping improve erosion resistance and extend service intervals.
Suitability for abrasive rotary control
A reduced bore ball control valve designed for highly abrasive rotary control applications, suitable for service in pulp and paper, petrochemical, refining, and related industries.
Wafer and lugged connections
Wafer and lugged connection options are available, allowing selection based on piping connection requirements.
Reduced leak paths and low emissions
The product design features reduced leak paths and low emissions, suitable for industrial applications with strict requirements on media emission control.
Installation notes
Prevent mechanical impact and installation stress on the ceramic flow path
During handling, lifting, positioning, pipe alignment, and connection, protect the valve from impact, levering, pipe misalignment, and other additional installation stresses. This helps prevent damage to the all-ceramic flow path and ceramic trim that could cause leakage or abnormal performance.
FAQ
What highly erosive media and service conditions are Neles E series ceramic ball valves suitable for?
The Neles E series is suitable for highly abrasive rotary control service such as slurries and fluids containing hard particles, targeting severe erosive conditions in pulp and paper, petrochemical, refining, and related industrial applications. Its full ceramic flow path helps withstand wear caused by particle erosion.
How is the full ceramic flow path of the Neles E series ceramic ball valve achieved?
The series is positioned as a full ceramic flow path product: the flow path and trim feature a next-generation ceramic lining with no wear-prone metal parts in the flow path, and the body is available in stainless steel or Mg-PS2 metal matrix composite. The ceramic construction helps extend plant run times and reduce maintenance costs, while reduced leak paths support low-emission operation.
How do I select a Neles E series ceramic ball valve based on pipe size and pressure rating?
The wafer-type E2 covers DN 25 to DN 100 (1-4 in.); the lugged E6 covers DN 25 to DN 200 (1-8 in.). Pressure ratings cover PN 10 to PN 40 and ASME 150 to 300. When selecting, verify the actual pipe diameter, piping pressure rating, media abrasiveness, and control conditions; specific configurations must be confirmed based on the actual model and application conditions.
What is the applicable temperature range of the Neles E series ceramic ball valve?
The temperature range of the series is -40 to +450 °C, corresponding to -40 to +840 °F. In actual use, confirm that the valve meets system conditions in light of media characteristics, pressure rating, and the specific model.
What design configurations and body materials does the Neles E series offer?
The Neles E series is a full ceramic flow path, reduced bore ball control valve available in wafer and lugged designs. Body materials include stainless steel and magnesium oxide, partially stabilized zirconia (Mg-PS2) metal matrix composite (MMC); specific design and material combinations must be confirmed based on the actual model and application conditions.
