High Temperature Ceramic Ball Valve FCCV2 - China Suppliers & Factory for Harsh Conditions
FCCV2 High Temperature Ceramic Ball Valve
The FCCV2 series high temperature ceramic ball valve is specifically developed for working conditions where standard ceramic valves cannot withstand extreme heat and rapid thermal shock. With a maximum service temperature of up to 456°C, this valve ensures safe and reliable operation in environments that combine high temperature, strong corrosion, and severe abrasion. It is widely applied in industries where conventional metal or alloy valves quickly fail, providing longer service life and reduced maintenance costs.
The FCCV2 features a fully hard-sealed structure without any non-metallic sealing materials such as graphite or PTFE, making it suitable for organic solvents, corrosive slurries, and aggressive chemical media. The precision-engineered ceramic ball and seat ensure tight sealing performance, even under fluctuating pressures and temperatures. Its "live load" packing system automatically compensates for wear, maintaining a constant sealing force and significantly extending packing life. Additionally, upper and lower sliding bearings in the packing box prevent displacement and packing squeeze, ensuring stable operation during frequent thermal cycles.

Frequently Asked Questions (FAQ)
What is the maximum operating temperature of the FCCV2 ceramic ball valve?
The FCCV2 high temperature ceramic ball valve supports a maximum service temperature of up to 456°C. It is specifically engineered for applications exceeding 180°C where standard ceramic or metal valves fail to perform reliably under extreme heat and rapid thermal shock.
Why does the FCCV2 not use graphite or PTFE sealing materials?
The FCCV2 adopts a fully hard-sealed structure with no non-metallic sealing materials such as graphite or PTFE. This design makes it compatible with organic solvents, highly corrosive slurries, and aggressive chemical media that would degrade conventional soft-seal materials, ensuring longer service life and wider chemical compatibility.
What is the "live load" packing system in the FCCV2 valve?
The "live load" packing system is a spring-loaded mechanism within the packing box that automatically compensates for packing wear over time. It maintains a constant sealing force regardless of wear, which significantly extends packing life and reduces maintenance frequency — especially important in high-temperature cycling environments.
Which industries are best suited for the FCCV2 high temperature ceramic ball valve?
The FCCV2 is widely used across multiple demanding industries, including: polysilicon production (silicon powder transport), petrochemical plants (hot corrosive slurries and catalyst transport), power generation and waste incineration (high-temperature desulfurization), and specialty chemical processes involving TiCl₄, FeCl₂, and reactive polymer mixtures.
What ceramic materials are available for the FCCV2 valve, and how do they differ?
The FCCV2 can be configured with several advanced ceramic materials including Y-TZP (Zirconia), Mg-PSZ, 90/95/99% Al₂O₃ (Alumina), Si₃N₄ (Silicon Nitride), and SiC (Silicon Carbide). Each material offers different combinations of hardness, flexural strength, thermal shock resistance, and corrosion resistance. For example, SiC offers the highest hardness (HRA 94) and excellent thermal shock resistance, while Mg-PSZ provides superior fracture toughness (13~15 MPa√m).
What sizes are available for the FCCV2 ceramic ball valve?
The FCCV2 is available in a wide range of nominal diameters from 1/2" (DN15) up to 10" (DN250). Both GB PN10 and HG PN10 flange standards are supported. The valve weight ranges from approximately 4.5 kg (DN15) to 290 kg (DN250), making it suitable for small-scale laboratory systems as well as large industrial pipelines.
