一、j641气动截止阀主要用途
缸使用介质：压缩空气，氮气。结构简单、制造和维护方便；工作行程小，启闭时间短；关闭体（阀瓣）与阀座密封面采用锥面密封，关闭力小，耐冲刷，密封可靠。阀座可为更换式阀座，可任意组合与关闭件密封面材料的配对，以满足工况要求，延长使用寿命。 

二、j641气动截止阀结构特点
   1、选材考究，符合国内、外相关标准，结构合理，造型美观。
   2、阀瓣、阀座密封面采用铁基合金堆焊或司太立（Slite）钴基硬质合金堆焊而成，耐磨、耐高温、耐腐蚀、抗擦伤性能好，使用寿命长。
   3、阀杆经调质及表面氮化处理，有良好的抗腐蚀性和抗擦伤性。
   4、可采用各种配管法兰标准及法兰密封面型式，满足各种工程需要及用户要求。
   5、阀体材料品种齐全，填料、垫片可根据实际工况或用户要求合理选配，能适用于各种压力、温度及介质工况。 
   6、倒密封采用螺纹连接密封座或本体堆焊奥氏体不锈钢而成，密封可靠，更换填料可在不停机情况下进行，方便快捷，不影响系统运行。
