Features:

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. We can fulfill the existing connection requirements of such as the face-

to-face dimensions and the flange type.

2. Ceramic fully lined

Ceramic components are assembled within the forged metal housing which absorbs the physical load and vibration of

the piping lines.

3. Various Actuation Types

Actuator is connected by a yoke interface that meets ISO 5211. Most all 1/4 turn actuation including pneumatic and

electric actuators. The yoke interface is re-movable and able to be easily modified to accommodate special

applications. Manual hand levers 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.And to obtain a long working life, we generally select the materials such as Hastelloy 276,

Inconel 625, Inconel 718 and even Zirconium for valve stems.

5. Abrasion Resistant

The hardness of 99.5% alumina ceramics is about HRA88 or above, harder than zirconia (about HRA85), about 8 times

harder than stainless steel. As valve core, ceramic components make the valve done well in the most severe abrasive

conditions, such as pneumatic conveying to transport silicon powder.

6. Ceramic-to-Ceramic spherical sealing face

The perfect spherical seal between the ceramic ball and seat 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 any

application, the equal percent V-port ceramic ball valve is the best choice.
