Q41H金属硬密封球阀特点：
1、手动部分可采用钢板压制的手柄或不锈钢铸造的手柄。手柄设有限位结构，在阀门开启、关闭的位置设定限位，当阀门使用在关键装置上时，限位块上设有锁孔可锁定开关位置避免误操作。手柄上有明显地开和关标识。
2、阀杆采用A182F（1Cr13）整体锻造并调制处理，硬度达到HB220～250。阀杆通过平键或花键或方契与手柄连接，通用性强，拆装方便。阀杆设有防吹出结构。
3、阀门的填料选用编结、柔性石墨密封圈或四氟烯密封圈，使得阀杆在一定的润滑情况下实现可靠的密封。
4、根据需要，球阀可设计成防静电结构，在球体与阀杆、阀杆与阀体之间设置导电弹簧，避免静电打火点燃易燃物质，确保系统安全。
5、密封副形式多样。根据不同工况可选用软密封、硬密封、防火阀座等结构；DN150以下为浮球形式，DN200以下为固定球形式。
6、球阀阀座处可设置辅助密封结构，在阀座和阀杆部位加装注脂阀，紧急情况下可暂时密封，并可根据需要加长阀杆以适宜埋地铺设得场所
