Applicable to XCMG loader transmission solenoid valve 272101035/SV98-T40S

Proportional solenoid valve is a new type of automatic control actuator with many design types. Common is the main body and pilot valve. The spool in the pilot valve is made into a certain taper. Then, the integrated displacement monitoring device and driving device are used to control the instantaneous oil volume, so as to achieve the purpose of indirectly controlling the oil volume of the main valve. The following brief introduction will introduce the function of the proportional solenoid valve and the working principle of the proportional solenoid valve.

Characteristics of proportional solenoid valves

1) It can realize the stepless adjustment of pressure and speed, and avoid the impact phenomenon when the normally open switch valve is reversed.

2) Remote control and program control can be realized.

3) Compared with intermittent control, the system is simplified and the components are greatly reduced.

4) Compared with the hydraulic proportional valve, it is small in size, light in weight, simple in structure and low in cost, but its response speed is much slower than the hydraulic system, and it is also sensitive to load changes.

5) Low power, low heat, low noise.

6) There will be no fire and no environmental pollution. It is less affected by temperature changes
