功能及用途：基于旋转阀芯工作原理，可根据要求达到流量特性，调节比可达 25：1。主要用于对气体介质（燃气、空气均可）的流量进行线性调节。

Function & Application: The linear flow control valve can achieve

optimal flow characteristic working by rotating the valve spool, it’s adjustable up to 25:1 ratio.

It’s mainly used to adjust the flow rate of gas medium (gas or air) in a linear way.
