FCCV7 Precision Control Ceramic Ball Valve
Structural characteristics and advantages
- ● 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 significantly stronger than conventional metal or composite ball designs, offering exceptional wear resistance in corrosive and erosive media.● Slotting design enables precision throttling of micro-flows, ensuring stability in dosing and continuous process operations.● 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.
