Operating Principle

PARKER proportional valve is the proportional electromagnet input voltage signal in the valve to produce a corresponding action, so that the working valve spool displacement, valve port size changes and complete the pressure and flow output components proportional to the input voltage. Spool displacement can also be fed back mechanically, hydraulically or electrically.

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.

Product Feature

Electro-hydraulic proportional valve has a variety of forms, easy to use electrical and computer control of various electro-hydraulic systems, high control accuracy, flexible installation and use, and strong anti-pollution ability, etc., the application field is widening. Electric proportional valve automatic selection and collection, the development of cartridge proportional valve and proportional multiway valve fully consider the characteristics of construction machinery, with pilot control, load sensing and pressure compensation functions. It is of great significance to improve the overall technical level of mobile hydraulic machinery. In particular, electric control operation, wireless remote control and wired remote control operation have shown good application prospects.
