Product Description

 

Product Description

The electro-hydraulic servo valve SV4-20 (15) 57-80/40-10-S451 for steam turbines is a special type of servo valve designed for steam turbine systems. Compared with conventional servo valves, it has the characteristics of high temperature and high pressure resistance, and can work stably and reliably. More precise control of flow and pressure can ensure stable operation of the steam turbine system under various load changes and operating conditions, and can quickly respond to changes in system demand.

In the steam turbine DEH system, the control circuit receives parameter information feedback from sensors, compares and calculates it with the preset target value, and generates corresponding control signals. By adjusting the working state and output of the servo valve, precise control of the hydraulic system is achieved. This process is usually a closed-loop feedback control system, where the control circuit continuously receives, processes, and adjusts control signals to maintain the hydraulic system in the desired operating state.
