Ceramic Ball Valve

Ceramic Ball Valve is used in high corrosive and high abrasive applications, such as lime slurry, fly ash pneumatic conveying system, PCI coal powder injection in steel plant.

Ceramic lined ball valve have excellent performance and much longer life time than soft seated and metal seated ball valves in most corrosive and abrasive applications.

Design Features:

1. Forged steel 3 piece body design:

Relia Ceramic lined ball valve can fulfill existing connection requirements such as face-to-face dimensions and customers’ existing flange type.

2. The wet parts are all ceramics—Ceramic fully lined:

Ceramic components are assembled into forged metal body of Floating Ceramic ball valve which absorbs most
physical loads and shock from piping lines.

3. Customized Actuation Types:

Actuator is connected to Floating Ceramic ball valve by a yoke that meets ISO 5211 specification including most pneumatic and electric actuators. The yoke is re-movable and easily modified to meet special requirements. Levers operated methods are also available for Ceramic lined ball valve.

4. Corrosion Resistant:

Cold Isostactic Pressing (CIP) and high-temperature sintering nanometer high-purity 99% Al2O3 and 99.7%
Al2O3 (alumina) and ZrO2 (zirconia) ceramics will not interact with almost all organic and inorganic chemicals, nor contaminate process medium. Their physically and chemically stability against most acids, salts and alkalis will last for many years with little or no corrosive degradation, which make sure that Ceramic ball valve have excellent performance in corrosive applications.

5. Abrasion Resistant:

The hardness of 99% alumina ceramics is about HRA88, harder than zirconia (about HRA85), solid tungsten
carbide is about HRA 90,which is about 8 times harder than stainless steel. As valve trim, ceramic components make Floating Ceramic lined ball valve work well in the most severe abrasive conditions, such as pneumatic conveying to transport silicon powder, coal powder, Mg powder, etc.

6. Ceramic-to-Ceramic spherical seated:

The perfect fine grinded spherical seal between ceramic ball and seat ensure a Class VI shutoff. The anti-scratch design between ball and seat, which prevent sealing surface from being scratched by particles. The ceramic ball will not be stuck so ball will not be broken.
