The servo valve SM4-20(15)57-80/40-10-S182 is a key hydraulic control component composed of electromagnetic valve, servo motor, valve core, valve seat, and other components. It plays an important role in regulating flow and pressure in hydraulic systems. Its high-performance design and reliability make it an ideal choice for hydraulic systems in many industrial and mechanical fields.
Function:
Whether in applications such as engineering machinery, metallurgical equipment, or automated production lines, the SM4-20(15)57-80/40-10-S182 servo valve can play an important role in improving the efficiency and accuracy of the system.
Structure:
The servo valve adopts a two-stage modular design and can be installed in integrated blocks or plates. Its design structure includes a symmetrical torque motor with double coils and four air gaps, as well as a four-way slide valve and valve sleeve with mechanical zero adjustment. The first stage nozzle baffle pilot valve is equipped with a torque motor that is fixed with six screws. The second stage adopts a four-way slide valve and valve sleeve structure, with mechanical zero adjustment function. Feedback the position of the valve core to the first stage through the feedback rod.
