The command signal is amplified by the proportional amplifier, and the current is proportionally output to the proportional electromagnet of the proportional valve. direction, so as to realize the position or speed control of the actuator. In some applications that require high position or speed accuracy, the displacement of the actuator can also be used.



The proportional valve is composed of a DC proportional electromagnet and a hydraulic valve. The core of the continuous control of the proportional valve is the use of a proportional electromagnet. There are many types of proportional electromagnets, but the working principle is basically the same. They are developed according to the control needs of the proportional valve. from.
