TECHNICAL SPECIFICATIONS FOR GE - DS3800DSAB

DS3800DSAB is a Servo Valve Module manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. A servo valve module is a critical component in a turbine control system that is responsible for regulating the flow of hydraulic fluid to control the positioning and speed of turbine components. In a turbine control system, the servo valve module is typically located in the hydraulic power unit, and it receives electrical signals from the control system's central processing unit (CPU) to adjust the flow of hydraulic fluid. The hydraulic fluid is used to control the position of the turbine's fuel and air control components, as well as the position of the turbine blades.

The servo valve module operates by using an electrical signal to control the movement of a spool inside the valve. This spool, in turn, controls the flow of hydraulic fluid through the valve to the turbine's actuators. The spool's movement is precisely controlled by the electrical signal, allowing the turbine control system to precisely adjust the position and speed of the turbine's components.

FEATURES:

Precision Control:

The servo valve module must be able to provide precise control of the flow of hydraulic fluid to the turbine's actuators. This requires the module to be able to adjust the flow rate of the fluid accurately and quickly in response to changes in the control signals it receives.

High Reliability:

Since the servo valve module is a critical component in the turbine control system, it must be highly reliable and able to operate continuously without failure. This requires the module to be constructed using high-quality materials and designed to withstand the harsh operating conditions found in a turbine environment.

High Flow Rates:

The servo valve module must be able to handle high flow rates of hydraulic fluid, which is necessary to provide sufficient force to actuate the turbine's components.

Low Hysteresis:

Hysteresis is the difference in the valve's opening and closing characteristics caused by the difference in the fluid's pressure. The servo valve module must have low hysteresis to ensure that the valve opens and closes smoothly, providing accurate control of the fluid flow.

Low Noise:

The servo valve module should operate with minimal noise to reduce any unwanted noise that could affect the turbine's operation.
