Why is the hydraulic control valve called hydraulic amplifier?
Hydraulic circuit of main circuit and control circuit, and the electrical control circuit is similar, electrical control circuit, main circuit and control circuit in the main loop of the control circuit of small current control of large current. In the same way, the hydraulic control circuit can also be used to control the large flow of the main circuit, while using small pressure to control the pressure. So hydraulic control valves are called hydraulic amplifiers.
If you look at the instructions, you understand that he's driving the 0-10v or the xma-yma current through the amplifier to get a large current or voltage drive
The function of liquid control can be called magnification. Electrically controlled, the amplification is a little strained. It depends on the function of different valves. In practical terms, we don't need to know whether the control valves are amplifying the components, and what aspects of them are being considered.
