Woodward 8407-105
Detailed Product Introduction: It is a professional electro-hydraulic proportional control actuator control unit under Woodward ProAct series, professionally matched with Woodward digital speed governors. The module receives digital speed regulation control signals from the governor, converts weak control signals into high-power hydraulic driving signals, accurately drives the steam valve, fuel gas valve and intake valve mechanical actuators, and realizes closed-loop precise adjustment of valve opening. It is the core execution component of turbine speed and load control.
