Product Description
Proportional valve, the full name is electro-hydraulic proportional valve, is a kind of hydraulic valve that converts the input electrical signal into force or displacement proportionally, so as to continuously control the pressure, flow and other parameters.
The proportional valve is composed of DC proportional electromagnet and hydraulic valve. The hydraulic valve part is little different from the general hydraulic valve, and the DC proportional electromagnet is different from the electromagnet used in the general solenoid valve, and the displacement output and suction output can be obtained proportional to the given current by using the proportional electromagnet. Proportional valve according to its control parameters can be divided into proportional pressure valve, proportional flow valve, proportional direction valve three categories.

Operating Principle
The command signal is amplified by the proportional amplifier, and the proportional output current to the proportional solenoid of the proportional valve, the proportional solenoid output force and the proportional movement of the valve core position, you can proportional control the flow of the liquid flow and change the direction of the liquid flow, so as to achieve the position or speed control of the actuator. In some applications requiring high position or speed accuracy, the closed-loop control system can also be formed by detecting the displacement or speed of the actuator.
Proportional valve is composed 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 variety, but the working principle is basically the same, they are developed according to the proportional valve control needs.
