The higher price of valve keeps hydraulic system overall cost relatively high;3, since the 3-position 4-way that proportional control valve is double electromagnet changes
It is automatically controlled considerably complicated in hydraulic circuit when executive component is more to valve, to be equipped with an amplification to each proportional control valve
Device or controller, electric control element cost are also relatively high.
If can go to control multiple executive components with a proportional control valve, the cost of hydraulic system and whole will be substantially reduced
Body size must have a kind of hydraulic valve real as soon as to realize the function of going to control multiple executive components with proportional control valve
The function of which executive component work can be now selected, and existing hydraulic directional valve is mostly actuator movement direction controlling,
Do not have the selection function of executive component.
