FCCV7 Precision Control Ceramic Ball Valve

The FCCV7 precision-control ceramic ball valve uses a slotted ceramic ball for low-flow regulation in corrosive, abrasive and particle-bearing media. Delivered data lists Cv below 10; stem-material and flange-standard options are detailed below.

    Design and construction

    • Tapered grooves on the ceramic ball core create flow regulation windows, providing extremely accurate control even at minimal flow levels.

      Coanda effect principle applied in the groove design prevents biased flow, reducing turbulence and erosion, while maintaining stable flow characteristics.

      Solid ceramic ball core is stronger than conventional metal or composite ball designs, offering wear resistance in corrosive and erosive media.

      Slotted ball meters small flows for dosing and continuous operation.

      Customizable stem materials (316L stainless steel, Hastelloy, Monel, titanium, zirconium, etc.) adapt to different chemical environments for optimal corrosion resistance.

      Flanged connection design supports multiple standards (DIN, ANSI, API, JIS) for global applicability.
