Regarding rhythmic opening of the valve when we supply to solenoid valve valve will move rooms valve immediately and end position allowing valve open or closed end position of his own or run an on-off time, but For additional Su Nation. Accessory Cable valve is opened by electrical signals that power valve to let more or less the 0-10 V dc power supply to the forward movement ด์ 0 v valve power to move forward ด์ 1 v valve room open valve. to 10% the oil flow from the valve to be only 10% (assumed).

When power supply to 5 V valve opening to half power to 10 V valve 100% open top allows the full flow of oil.

The postponement of the valve. Commander will affect flow Of oil to the cylinder is more or less out fast or slow motion by controlling the electrical signal.

Proprotional valve diagram

He called the proprotional valve, it is proportional to electrical signals.

Objective: Fundamental and Explain proportional valve principles and make basic adjustments

Activity: User learning and understanding in valve disassembly, inspection and reassembly

Picture below show process of valve.

I ‘m going to try in present about cylinder and hydraulic information update,news,product review to you .
