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。
