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.
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 seated
The perfect fine grinded 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 V-port ceramic ball valve with equal percent characteristics may be the best choice.
