2.非直接作用式安全阀这类安全阀可以分为先导式安全阀、带动力辅助装置的安全阀。先导式安全阀是依靠从导阀排出的介质来驱动或控制的。而导阀本身是一个直接作用式安全阀，有时也采用其他形式的阀门。先导式安全阀适用于高压、大口径的场合。R900521576DBE10-5X/200YG24Z4MR900517820DBE10-5X/200YG24Z4VR901069892DBE10-5X/315XYG24K4MR900924161DBE10-5X/315XYG24NK4MR900579202DBE10-5X/315XYG24Z4MR900916124DBE10-5X/315YG24K4MR900978551DBE10-5X/315YG24K4VR900949005DBE10-5X/315YG24NK4MR901058477DBE10-5X/315YG24NK4VR900534917DBE10-5X/315YG24NZ4MR900900524DBE10-5X/315YG24NZ4VR900528731DBE10-5X/315YG24Z4MR900533043DBE10-5X/315YG24Z4VR900704605DBE10-5X/350XYG24K4MR900967563DBE10-5X/350YG24K4MR900957752DBE10-5X/350YG24NK4MR900538008DBE10-5X/350YG24NZ4MR900539401DBE10-5X/350YG24Z4MR900926160DBE10-5X/350YG24Z4VR900916125DBE10-5X/50XYG24K4M)
