The introduction and development of hydraulic technology, equipment manufacturing and other areas to improve performance and level, as a manufacturing power to "manufacturing power" across the country, if we want to become a real manufacturing power in the global context, we must become a power in the hydraulic industry. This is a historical choice, but also the development of China's equipment manufacturing industry opportunities and challenges.

Features: fast response; small impact; compact structure; good stability; low noise, easy to realize the overload protection.

Working principle: servo controller will come from the signal source command signal and speed generator motor speed feedback signal error signal amplification, at the same time and drive the electro-hydraulic servo valve, hydraulic press through the electro-hydraulic servo valve to complete the hydraulic power amplification and drive the hydraulic motor to rotate, the speed of the hydraulic motor by the speed generator to measure the feedback to the servo controller to achieve the speed of the motor electro-hydraulic servo control.

Application: Hydraulic servo valves are widely used in all kinds of machine tools. Such as punching machines, lathes, milling machines, etc., can realize the high precision and high efficiency control of workpiece processing.
