Z41W不锈钢闸阀
概述
高中压法兰连接的闸阀适用于公称压力PN1.6～16.0MPa,工作温度≤-29℃～550℃的石油、化工、水力、火力电站各种系统的管路上，切断或接通管路介质。适用介质为：水、油品、蒸气、及酸、碱、氨、尿素、含硫天然气等。结构特点
1、选材考究，符合国内外相关标准，材料的全面质量高。
2、符合国内外先进标准的要求，密封可靠、性能优良、造型美观。
3、密封副配对先进合理，闸板和阀座的密封面采用不同硬度的司太立（Stellite）钴基硬质合金堆焊而成，密封可靠、硬度高、耐磨、耐高温、耐腐蚀、抗擦伤性能好、寿命长。
4、阀杆经调质及表面氮化处理，有良好的抗腐蚀性、抗擦伤性和耐磨性。
5、采用楔式弹性闸板结构，中大口径设置推力轴承，磨擦力小，并配有撞击手轮，启闭轻松自如。
6、可采用各种配管法兰标准及法兰密封面形式，满足各种工程需要及用户要求。
