The Design of a Rotary Wheel Servo Valve

The vibration device is the vital part in hydraulic linear friction welder. To improve its friction vibration servo system performance, i.e. the high frequency working ability of the servo valve, a new kind of rotary wheel servo valve with high frequency characteristics was put forward. It possesses the potential to improve the performance of hydraulic linear friction welding machine, explore the linear friction welding technology in much broader industrial areas.
