撞击式带轴承大口径截止阀概述：
撞击式(带轴承)大口径截止阀结构先辈、密封可靠、性能精良、造型美观。分外是启闭采用了活络连接结构，极大进步阀杆的钢度，明显降低了噪音和振动，进步了阀门的使用寿命与各项性能。可以安装管道的任何位置上，介质可在任意方向通过。
1.DN250以上采用先辈的多密封，双支架，采用导向活动（能极大进步抗水锤冲击）、介质从上方进入，交好解决了大口径截止阀启闭力距大，密封无法关严，填料室跑冒、漏等题目，有力进步了阀门各项性能与使用范围。（“关”的力矩是通俗阀门的10%“开”的力矩是通俗阀门的3%）。
2.不锈钢截止阀适用于各类腐蚀性介质的管道上，有优秀的防腐蚀性和充足的强度。
3.合金钢截止阀适用于耐高温耐的蒸气、油品管道上，具有耐高温特点广泛应用于给排水、冶金、蒸汽、电力、石油化工等行业，是当代工业中理想的通用管道控制部件。
