Product Description
With the development of hydraulic transmission and hydraulic servo systems, some hydraulic systems that require continuous control of pressure, flow and direction without high control accuracy have appeared in production practice. Since the ordinary hydraulic components can not be full enough to have certain servo requirements, and the use of electro-hydraulic servo valves is too wasteful because the control accuracy requirements are not high, a proportional control valve between the ordinary hydraulic components (switch control) and the servo valve (continuous control) has been produced in recent years.
Electro-hydraulic proportional control valve (referred to as proportional valve) is a kind of cheap electro-hydraulic control valve with good anti-pollution performance. The development of proportional valve experiences two ways, one is to replace the manual adjustment input mechanism of the traditional hydraulic valve with proportional electromagnet, on the basis of the traditional hydraulic valve: the development of a variety of proportional direction, pressure and flow valves; The second is that some original electro-hydraulic servo valve manufacturers developed after reducing the design and manufacturing accuracy on the basis of electro-hydraulic servo valves.
Working 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.
