(耐磨，耐酸碱)进口气动陶瓷球阀核心部件阀芯与阀座采用氧化铝陶瓷或碳化硅陶瓷，经平面磨、外圆磨、快速球磨、球面对研等工序精密加工，阀芯与几乎完全贴合的阀座相对旋转实现启闭，轻扭矩得以精妙展现(Wear
resistant, acid and alkali resistant) The core components of the imported
pneumatic ceramic ball valve, the valve core and valve seat, are made of
aluminum oxide ceramics or silicon carbide ceramics. After precision processing
of surface grinding, cylindrical grinding, rapid ball grinding, ball surface
grinding and other processes, the valve core and the almost completely fitted
valve seat rotate relatively to realize opening and closing, and the light
torque is subtly displayed
