Overview：
ABB SPHSS13 Hydraulic Servo Module
ABB SPHSS13 Hydraulic Servo Module is an intelligent valve position control module and is a core drive component in turbine mechanical speed and load control systems. The SPHSS13 can automatically or manually control hydraulic actuators, provide an interface for HR series controllers, and drive servo valves or current/hydraulic (I/H) converters.
Note: The ABB SPHSS13 Hydraulic Servo Module is often used in conjunction with the SPTPS13 Speed Detection Module to form a turbine speed control system.

Function & Features：
- Intelligent Control Unit: The ABB SPHSS13 Module is equipped with a microprocessor, memory, and communication circuits, making it an intelligent I/O device capable of independently processing control algorithms and signals.
- Position Control: The ABB SPHSS13 controls the position of hydraulic actuators by adjusting the current output to the servo valve, thereby achieving closed-loop control of valve opening, fuel/steam flow, and ultimately the unit speed.
- Feedback Interface: The ABB SPHSS13 can be directly connected to a Linear Variable Differential Transformer (LVDT) as a position feedback sensor.
Specific Applications of the ABB SPHSS13 (Valve/Actuator Control)
The SPHSS13 module controls hydraulic actuators by driving servo valves or I/H converters, and can be applied to valves or mechanisms as follows:
- Fuel Control Valve: Regulates the flow of natural gas or liquid fuel to control unit power, speed, and emissions.
- Inlet Guide Vanes: Adjusts the angle and flow of air entering the compressor to optimize efficiency and prevent surge.
- Exhaust/Bypass Valve: Regulates the thermal cycle during startup, shutdown, or varying operating conditions.
- Main Steam Valve/Speed Control Valve: Controls the flow and pressure of steam entering the turbine, enabling speed and load regulation.
- Extraction Steam Control Valve: In combined heat and power (CHP) units, controls the pressure and flow of industrial or heating steam extraction.
- Centrifugal Compressor Surge Control Valve: Opens the surge control valve to protect the compressor from surge conditions.
