(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(jīng)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(zhuǎn)實現(xiàn)啟閉，輕扭矩得以精妙展現(xiàn)(Wearresistant, acid and alkali resistant) The core components of the importedpneumatic ceramic ball valve, the valve core and valve seat, are made ofaluminum oxide ceramics or silicon carbide ceramics. After precision processingof surface grinding, cylindrical grinding, rapid ball grinding, ball surfacegrinding and other processes, the valve core and the almost completely fittedvalve seat rotate relatively to realize opening and closing, and the lighttorque is subtly displayed
