(耐磨，耐酸堿)進口氣動陶瓷球閥核心部件閥芯與閥座采用氧化鋁陶瓷或碳化硅陶瓷，經平面磨、外圓磨、快速球磨、球面對研等工序精密加工，閥芯與幾乎完全貼合的閥座相對旋轉實現啟閉，輕扭矩得以精妙展現(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
