供应中南J41H-16C截止阀
扬州中南截止阀、法兰截止阀、手动截止阀
法兰截止阀结构特点
1、法兰截止阀选材考究，符合国内、外相关标准，结构合理，造型美观。
2、法兰截止阀阀瓣、阀座密封面采用铁基合金堆焊或司太立（Stellite）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。
4、法兰截止阀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。
5、法兰截止阀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。
6、法兰截止阀阀体材料品种齐全，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。
7、法兰截止阀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。
