YK43X/F/Y gas valve
Product Name:
YK43X/F/Y gas valve
Description:

 

一、产品[先导活塞式气体减压阀]的详细资料:
产品型号:YK43X/F/Y型
产品名称:先导活塞式气体减压阀
产品特点:本系列减压阀属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化,通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小,实现减压稳压功能。本产品主要用于气体管路,如空气、氮气、氧气、氢气、液化气、天然气等气体。
