Product Description
Woodward 8405-029 Actuator
Product Overview
- The Woodward 8405-029 is an electrically powered actuator, part of Woodward’s actuator family designed for precise control of engine or turbine fuel systems in industrial applications such as power generation, marine propulsion, and industrial processes. This actuator is typically used with Woodward’s electronic governors or control systems (e.g., 2301D, ProAct, or 723PLUS series) to regulate fuel or air flow for diesel, gas, or dual-fuel engines, or small turbines. The 8405-029 provides reliable and responsive positioning with a robust design suitable for demanding environments. Compared to other Woodward actuators like the 8404-201 or 8404-205, the 8405-029 may feature specific differences in torque output, stroke range, or environmental certifications, potentially tailored for unique engine or turbine requirements. It is distinct from Woodward’s digital control systems (e.g., 8273-1011, 8200-1300), Peak150 series (e.g., 8200-176), ProAct series controls (e.g., 8237-2595), and other actuators like the EPG series (e.g., 8290-195), focusing specifically on actuation for precise throttle or valve control.
