1. 3PC body design
 The three piece design of the valves allows direct connection to the existing pipelines without the need for pipe reducers in front and behind the valve.  A standard Foyo ceramic ball valve is flanged according to ASME B16.5, but we can also fulfill the existing connection requirements of such as the face-to-face dimensions and the different  flange type.
2. Forged steel with ceramic fully lined
 High pure alumina or zirconia ceramic components(ball, seats, bushing and flange liner) are assembled within the forged steel housing which absorbs the physical load and vibration of the piping lines.  

3. Various Actuation Types
Actuator is connected with the valve body thru a yoke interface that meets ISO 5211. Most all 1/4 turn actuation including pneumatic and electric actuators. The yoke interface is removable and able to be easily modified to accommodate special applications. hand lever and gear boxes are also available.

4. Corrosion Resistant
Cold Isotactic Pressing (CIP) and high-temperature sintering nanometer high-purity 99.5% alumina and zirconia ceramics will not interact with almost all organic and inorganic chemicals, nor contaminate the process media. Their physically and chemically stability against most acids and alkalis will last for many years with little or no corrosive degradation.

5. Abrasion and errosion Resistant
The hardness of 99.5% alumina ceramics is about HRA88 or above, harder than zirconia (about HRA85), and it is about 8 times harder than stainless steel. As valve trim, ceramic components make the valve done well in the most severe abrasive and errosion conditions, such as pneumatic conveying to transport silicon powder,and  flu gas desulfurization (FGD) in power plant.

6. Ceramic-to-Ceramic spherical hard seated
The perfect spherical seal between the fine ceramic ball and seats ensure a Class VI shutoff.   The anti-scratch design between the  ball and seat,  which  prevent  the  deep  sealing  surface being marred and scratched by particles , and the ceramic  ball will not  be stuck anyway. 

7. V-port balls and Round-port balls

FOYO offers each line size two different trims: Round-port and V-Port. In general, the round-port ceramic ball valve is often used as an on-off valve.  If precise and stable control  performance are highly required in the application, the equal percent V-port ceramic ball valve is the best choice.
