Three-piece forged body
Forged body avoids cast defect of cast body;
O-port & V-port ball
O-port ball mainly used as shut off function;
V-port ball mainly used as control function;
V-port ball can cut off fiber to avoid blocking;
Ball in material of
Ball requires material with high flexural strength;
Ceramic ZrO2 has higher flexural strength than Ceramic
Seat in material of
Seat requires material with high pressure resistance.
Ceramic Al2O3 has higher pressure resistance than Ceramic
Body fully lined with
Body fully lined with ceramic Al2O3 is protected from wear
The 99% Al2O3 and ZrO2 ceramics are inert to almost all
organic and inorganic chemicals except hydrofluoric acid.
The Silicon carbide ceramic is resistant to hydrofluoric
Strong stability in strong acid, strong alkali and strong
corrosive slurry avoids pollution to the service.
The 99% Al2O3 ceramic with hardness of HRA88 and the ZrO2
ceramic with hardness of HRA85 are many times harder than stainless steel and cemented
The extreme hardness makes the ceramic with high wear
resistance against friction in pneumatic conveying of powder and abrasive
slurry with hard solid content in industries of steel, metallurgy,
petrochemical, mining, power plant, paper, pulp and polysilicon etc.
Through precise grinding, the ceramic ball closes tightly to
the ceramic seat to achieve zero leakage (class VI).
There is no any space between the ball and seat to avoid
Small operate torque
The characteristic of high hardness and extreme low surface
roughness reduces the friction coefficient of sealing face and the operate
torque of valve.
Equipped with ISO 5211 mounted pad
Pneumatic actuator and electric actuator can be connected
with the ball valve through ISO 5211 mounted pad.
