Principle description:
When the command signal by the proportional amplifier for power amplification, and proportional output current to the proportional solenoid of the proportional valve, the proportional solenoid output force and proportional movement of the valve line mechanism of the displacement or speed detection, constitute a closed-loop control system.
Proportional valve consists of DC proportional solenoid and hydraulic valve two parts. Proportional valve to achieve continuous control of the core is the use of proportional solenoid, proportional solenoid types of core position, you can proportionally control the flow of liquid and change the direction of liquid flow, thereby realizing the position or speed control of the actuator.
In some of the position or speed of the degree of higher requirements of the application, but also through the executive, but the working principle is basically the same, they are based on the control needs of the proportional valve developed.
