proportional valve circuit

Experimental results have shown that the system features precise speed control and simple design as compared to the sensing circuit controlled by T-type proportional speed regulation valve.

试验结果表明，与比例三通调速阀控制的敏感回路相比，该系统速度控制精度高，结构简单。

This output transferred thorough PWM driver circuit and changed into current signal to the proportional magnetic valve.
