金属硬密封气动蝶阀采用碳钢材料，三偏心结构，由阀体、蝶板、密封圈、气动执行器等主要部件组成。标准型号有D643H、D643W型（法兰连接）和D673H、D673W型（对夹连接）。气动硬密封蝶阀寿命长、自控节能，产品符合国家标准JB/T8527-1997金属密封蝶阀和GB/T13927-2008通用阀门压力试验标准及阀门其它相关标准的规定。铸钢气动硬密封蝶阀的蝶板由弹性密封和硬软多层密封兼容的加工新工艺制成，使蝶阀在运行工作时，减少其扭矩力，达到省力，节能之功能。从而确保整体的抗腐蚀、耐高温、抗磨损的可靠性。
二、D643H、D643W硬密封气动蝶阀主要性能特点：
1、结构独特、型小轻便、操作灵活、省力方便；
2、密封可靠，可达到气密封无泄漏；
3、流量特性趋于直线调节性；
4、采用三偏心原理，使密封面近似零磨损，延长了阀门的使用寿命；
5、应用范围广。如：可用于水、蒸气、油品、空气、煤气等介质。
6、适用不同温度及6.4MPa以下的压力等级，耐腐蚀等各种介质管线。
三、D643H、D643W硬密封气动蝶阀的用途：
本蝶阀适用于食品、医药、石油化工、电厂、钢厂、工业环保水处理及高层建筑、供排水管道上作调节流量和截断流体最佳装置。D73H/D373H/D673H/D973H-(6、10)C、P、R、V系列对夹式金属硬密封蝶阀
