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 operating conditions are suitable for the neles E-Series ceramic ball valve?
The neles E-Series is suitable for highly abrasive rotary control applications involving slurries and fluids containing hard particles. It is designed for severe erosive conditions in pulp and paper, petrochemical, refining, and related industrial applications. Its ceramic flow path and trim help withstand wear caused by particle erosion.
What value does the ceramic flow path of the neles E-Series ceramic ball valve provide for operation and maintenance?
The series uses next-generation ceramic-lined flow paths and trim for highly abrasive rotary control applications. Ceramic valves help extend plant operating cycles, prolong valve service life, and reduce maintenance costs. They also support low-emission operation by minimizing potential leak paths.
How should the neles E-Series ceramic ball valve be selected according to pipe size and pressure class?
The wafer E2 size range is DN 25 to DN 100, equivalent to 1 inch to 4 inches. Pressure classes cover PN 10 to PN 40 and ASME 150 to 300. Selection should consider the actual pipe diameter, piping pressure class, media abrasiveness, and control conditions. The specific configuration must be confirmed according to the actual model and application requirements.
What temperature range is supported by the neles E-Series ceramic ball valve?
The series supports a temperature range of -40 to +450 °C, corresponding to -40 to +840 °F. During actual operation, confirm that the valve meets system requirements based on the media characteristics, pressure class, and specific model.
What configurations and valve body materials are available for the neles E-Series?
The neles E-Series is a reduced-bore ceramic-flow-path ball control valve available with wafer and lug configurations. The wafer E2 version covers DN 25 to DN 100. Valve body materials include stainless steel and metal matrix composite (MMC) material made from magnesium oxide and partially stabilized zirconia (Mg-PS2). The specific configuration and material combination must be confirmed according to the actual model and application requirements.
