Valvola a sfera in ceramica di tipo flottante

Specifica:

Applicazioni tipiche:

In molte applicazioni corrosive e / e abrasive, Vengono utilizzate valvole a sfera rivestite in PTFE o PFA e valvole a sfera con sede metallica, ma limitato al materiale, queste valvole a sfera rivestite in PTFE o PFA e le valvole con sede in metallo non possono durare a lungo a causa della forte abrasione e corrosione. Floating Ceramic ball valve have excellent performance and much longer life time than soft seated and metal seated ball valves in most corrosive and abrasive applications. Alcune applicazioni tipiche elencate di seguito (ma non limitato a queste applicazioni) where FUVALVE Floating Ceramic ball valve have been widely used all over the world: Polvere di silicone,Polvere di allumina,Polvere di carbone secca,Liquami calcarei,Liquame di gesso,Gesso,Fly Ash,Mining Ore,Iniezione di polvere di carbone,Polvere metallurgica,Centrale termoelettrica FGD,Catalizzatore solido di petrolio,Sospensione di TiO2 con acido solforico,Soluzione di ammoniaca con polvere,Acido cloridrico,Cloro liquido,Bulk Material.

Caratteristiche del progetto:

1. Forged steel 3 piece body design:

FUVALVE Floating Valvola a sfera in ceramica can fulfill existing connection requirements such as face-to-face dimensions and customers’ existing flange type.

2. The wet parts are all ceramics—Ceramica completamente foderata:

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 Floating Ceramic ball valve.

4. Corrosion Resistant:

Cold Isostactic Pressing (CIP) and high-temperature sintering nanometer high-purity 99% Al2O3 and 99.7% Al2O3 (allumina) 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 Floating 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 ball valve work well in the most severe abrasive conditions, such as pneumatic conveying to transport silicon powder, coal powder, Mg powder, eccetera.

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.

7. V-port balls and Round-port balls:

FUVALVE offers all size of Floating Ceramic ball valve two different port: Round-port and V-Port balls. In general, the round-port ceramic ball valve is often used as an on-off valve. If precise and stable control performance is required in any corrosive and abrasive applications, V-port Floating Ceramic ball valve with equal percent characteristics may be the best choice.
