简述：API美标截止阀适用于公称压力PN1.6~16MPa(Class150~Class2500),工作温度≤600℃的石油、化工、制药、化肥、电力行业等各种工况的管路上，切断或接通管路介质。
产品特点：
1、产品结构合理、密封可靠、性能优良、造型美观。
2、密封面堆焊Co基硬合金，耐磨、耐蚀、抗擦伤性能好，使用寿命长。
3、阀杆经调质及表面淡化处理，有良好的抗腐蚀性及抗擦伤性。
4、公称压力≥25.0MPa(Class150)中腔采用自密封式结构，密封性能随压力升高而增强，保证了密封性能。
5、阀门设有倒密封结构，密封可靠。
6、零件材质及法兰、对焊端尺寸可根据实际工况或用户要求合理选配，满足各种工程需要。
