Eccentric Semi Ball Valve - China

Eccentric semi-ball valve is a kind of new developed ball valve which is specialized in solving the technical problems during “solid-gas” and “liquid-gas” fluids medium conveying.

It is mainly used for cutting off, regulating or changing the direction of medium in the pipeline.

Eccentric semi-ball valve is widely used in steel mill, alumina plant, soda plant, water works and so on.

Benefits

1 - With straight through type valve body, this valve can keep the medium flow by linear when the valve fully opened, so it reduced less energy loss compared with other valves.

2 - Easy to operate: As the valve disc moved away from valve seat without any contact, so it has smaller starting torque compared with O type ball valve and easy to operate.

3 - Because of double eccentric structure design, the semi-ball valve is perfectly sealed and can be closed tightly .

4 - When the valve is closed, the wedding force is able to remove the foreign materials, therefore it has anti-scaling performance.
