Introduction

FREE-VALVE’s manual operation ceramic lined ball valves are designed with engineering ceramics the engineering ceramics internal parts provide excellent wear resistance, the ceramic ball valves are widely used as an open and close function as well as a throttling control tasks in corrosive medium with abrasive solids content.  

Advantage
1.The hardness of the ceramic material can be higher than HRC80.
2.Engineering internal parts of ceramic ball valve provide superior protection from corrosive and abrasive medium.
3.The manual lever or gear box is installed on the ceramic ball valve .Limit block is installed on the valve body operated by manual lever,the limit block can prevent valve from excessive-opening or excessive- closing,the words of open and close direction are displayed on the limit block.
4.The valve has a floating ball design, the ball is floating, the ball has a defined clearance and is pressed against the downstream seat under the differential pressure to achieve sealing.
5.Zirconia ceramic with inherent self-lubrication, valve opening and closing torque is less than the ball valve with metal seat.



Applications
FREE-VALVE’s manual operation ceramic lined ball valves are suitable for Silicon Powder, Alumina Powder, Dry Coal Powder, Limestone Slurry, Gypsum Slurry, Plaster, Fly Ash, Mining Ore, Coal Powder Injection, Metallurgical dust, Thermal Power plant FGD , LiCoO2 powder equipment.
