一、进口美标安全阀产品概述 品牌：美国威盾VTON 进口美标安全阀，American Standard safety valve，是指按照美标ANSI及API规范设计制造，压力为150LB,300LB,600LB,900LB,1500LB，用于管道，储罐，或者设备的超压保护装置的安全阀。 美国威盾VTON美标安全阀按API RP520设计，适用大部分常规介质的工矿条件，采用伞形反冲盘设计，能够有效地提高排放压力，阀瓣能在较小的超压下迅速达到全启的高度，从而达到额定排量；阀座和阀瓣的密封面堆焊硬质合金，再经精心研磨后保证安全阀的密封性和使用寿命。
二、进口美标安全阀产品特征 1、美标安全阀阀座与阀体为可分离式，维修方便、经济 2、美标安全阀伞形反冲盘和调节圈能够有效地提高升力，阀瓣在较小超压下就能够迅速全开启，排放介质，从而达到保护设备的目的 3、美标安全阀调节圈能够调整满意的启闭压差 4、美标安全阀对反冲盘和导套、阀杆和调整螺钉的材料进行合适的选择以及间隙的适当选取，保证阀瓣的运动灵活 5、美标安全阀密封面处堆焊硬质合金，表面精研后保证了安全阀的耐蚀性、高密封性和使用寿命长 6、美标安全阀弹簧和波纹管选材及加工工艺讲究，并进行严格的测试和检查
