(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
进口气动陶瓷球阀产品详情 Product details
(球及阀座原料采用刚玉陶瓷（成分为Al，O≥95%）或碳化硅 The material of ball and valve seat is Corundum Ceramic(Main content Al,O.≥95%)or Silicon Carbide
陶瓷经1680℃以上超高温烧结而成，硬度高达HRA85° Ceramic is fritted at 1680℃, hardness is up to HRA85°
毛坯经过精密的研磨成型，研磨后的球度为0.005mm Semifinished product is grinded precisely. The sphericity after grinding is 5um
阀芯球体与球座配合研磨，轻扭矩与硬密封完美结合 The ceramic ball and seat are grinded in pair which makes it have the advantage of low torque and good hard sealing
阀体通过CNC机床精密加工，与陶瓷球芯准确配合 The valve body is precisely processed by CNC machine tool, and accurately matched with the ceramic ball core
产品严格通过严格的气压密封测试和水压密封测试 of the products have passed the strict air pressure seal test and water pressure seal test
