Product Description

 

Product Description

Servo valve S15FOFA4VBL is an electro-hydraulic servo valve specifically designed for high and medium pressure control valves in steam turbines, also known as the control system electro-hydraulic servo valve. It plays a crucial role in the high and medium pressure systems of steam turbines, used for automatic regulation and control of system pressure.

By accurately controlling the pressure of the high and medium pressure system of the steam turbine, the servo valve S15FOFA4VBL can ensure the stable operation of the steam turbine under different loads and working conditions. It can respond to changes in system pressure and adjust the valve opening in a timely manner to maintain the system within the set pressure range. This helps to improve the efficiency, reliability, and safety of steam turbines, while reducing energy waste.

Product Features:

- High performance, sensitive response, and fast response enable it to quickly adjust the flow and pressure of the hydraulic system in the control system to meet precise control requirements.

- Strong anti-interference ability ensures the stability and reliability of the system.

- It can provide stable hydraulic transmission, avoid severe flow fluctuations and hydraulic impacts, thereby ensuring the stability and reliability of the system.

- Good dynamic response, able to quickly respond to changes in control signals, and adjust the working status of the hydraulic system in a short period of time.

Applications of Servo Valve:

1. Load control: According to changes in load demand, the DEH system will generate corresponding control signals and adjust the valve opening through servo valves to achieve load regulation.

2. Pressure regulation: Servo valves are also used in DEH systems to control system pressure.

3. Stability control: In the DEH system, the servo valve can quickly respond to control signals, adjust the valve opening to adapt to changes in system load and pressure, and thus maintain the stability of the steam turbine.
