Q941TC Electric Ceramic Ball Valve summary

Q941TC electric ceramic ball valve produced and sold by Baicang Valve Group has the characteristics of corrosion resistance, wear resistance and erosion resistance.It is the best choice of granular fiber medium and strong corrosive medium!

(1) All the parts in contact with the medium are structural ceramic materials, whose chemical stability and hardness are very high (Rockwell hardness HRC90), second only to diamond.
Therefore, the valve has high wear resistance, corrosion resistance, erosion resistance, and good thermal insulation, small thermal expansion.
(2) The ball is made of grinding equipment and process, the ball has high precision of roundness and good surface quality. After grinding with the valve seat, it can obtain good sealing performance by using the self-smoothness of ZR02 ceramic.
(3) completely changed the metal hard seal ball valve easy to leak, torque, sealing surface corrosion resistance shortcomings.
(4) ceramic good wear resistance, so that the valve durable, high reliability.
Long service life, is titanium alloy valve and Monel valve 2-4 times.
(5) used in high hardness granular medium, or soft particles but corrosive medium.
