In the fields of modern industrial automation and mechanical engineering, precise control is the key to improving efficiency and performance. The electro-hydraulic servo valve G761-3033B is one of the solutions to meet such control demands. Below, we will delve into the working principle, main parameters, and its importance in industrial applications of the G761-3033B servo valve.

The electro-hydraulic servo valve G761-3033B is a precise control component that converts electrical signals into hydraulic action. Its working principle is based on a simple mechanical feedback mechanism:

1. When an electrical signal is input, the armature moves under the action of electromagnetic force, driving the diaphragm connected to it to rotate.

2. The rotation of the diaphragm causes it to move closer or farther from the nozzle, thereby changing the oil discharge area of the nozzle.

3. Reducing the oil discharge area increases the oil pressure in front of the nozzle, while increasing the oil discharge area reduces the oil pressure.

4. This change in oil pressure is then converted into a torque signal, ultimately producing precise mechanical displacement, achieving accurate control of the hydraulic system.

Main Parameters
