Pneumatic ball valve for dust collection system in iron and steel industry

Pneumatic  ball valve for dust collection system in steel industry  is a high performance ball valve designed  for  pneumatic ash conveying pipe in a gas bag-type dedusting system of a blast furnace ,which solves the difficulties of transporting of "solid-gas" two phase medium.It is widely applied fly ash transportation at cloth bag type dust collection system in the iron and steel industry. 

BENEFITS 

1.With straight through type valve body ,this valve can keep the fluid flow by linear when the valve fully opened with out any blockage,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 segment ball valve is perfectly sealed and can be closed tightly .

4.When the valve is closed ,the welding force is able to remove the foreign materials ,therefore it has anti-scaling performance and prevent blockage dust removing device.

5. The weight is light compare to O type ball valve ,so it reduced the cost of maintenance and man power.

6. Special  hard alloy material can be spraied to keep the valve have anti-abrasive performance .
