Information
In the transportation of silicon polysilicon valve, the ball is easily wrapped by silicon powder, which causes problems such as leakage. Due to the high hardness of silicon powder, the service life of general ball valves is very short. In response to this situation, KW has specially developed and designed a special valve suitable for the transportation of polysilicon powder. The strong corrosion resistance of structural ceramics and the highly corrosion-resistant material of zirconium alloy make the life of the new valve 6 times longer than that of the original valve. Many, efficiently improve the equipment management of solar polysilicon powder transportation!
Structural features
All parts in contact with the medium are structural ceramic materials, which have extremely high chemical stability and hardness (Rockwell hardness HRC90), second only to diamond. Therefore, the polysilicon special valve produced by KW company has extremely high wear resistance, corrosion resistance, erosion resistance, good thermal insulation and small thermal expansion. The ball is manufactured with advanced grinding equipment and technology. The ball has high roundness accuracy and good surface quality. After being researched with the valve seat, the self-lubricity of Zr02 ceramic can be used to obtain good sealing performance. The shortcomings of the metal hard-sealed ball valve are easy to leak, the torque is large, and the sealing surface is not resistant to corrosion. The good abrasion resistance of ceramics makes this valve durable and extremely reliable. It has a long service life, which is 2-4 times that of titanium alloy valves and Monel valves. Used in high hardness granular media, or soft particles but corrosive media, this valve has unparalleled absolute advantages, and it is currently the only valve suitable for such media.
