Product Overview

The WOODWARD 9907-1608 is an electro-hydraulic actuator, specifically known by its detailed model name V45TS-1010-MUEXM-X-S-X. This particular model is a double-acting, rotary actuator. This means it utilizes hydraulic pressure to achieve precise rotational movement in both directions.

Actuators like the 9907-1608 are fundamental in industrial control loops. They take electrical commands from a control system, such as a governor or a programmable logic controller (PLC), and convert them into the exact physical motion needed to operate control valves, dampers, or other mechanisms. These are vital for regulating fluid flow or mechanical position in critical industrial machinery, especially large prime movers like gas turbines, steam turbines, or large industrial engines.

• Type: Electro-Hydraulic Actuator (Rotary, Double-Acting)
• Manufacturer: Woodward
• Model Number: 9907-1608 (detailed as V45TS-1010-MUEXM-X-S-X)
• Primary Function: Converts electrical control signals into precise, high-force physical rotation to position a valve, damper, or other controlled device, commonly used in demanding turbomachinery and large engine applications.

Detailed Product Description

In complex industrial environments, especially those involving high-value assets like gas turbines, steam turbines, or large industrial engines, the ability to rapidly and accurately manipulate fuel, air, or steam flow is absolutely critical for optimal performance and safety. The WOODWARD 9907-1608 is specifically engineered for these vital roles. It acts as the robust link between sophisticated electronic control systems and the physical components that perform real-time adjustments to operational parameters.

The V45TS series, to which the 9907-1608 belongs, is highly regarded for its rotary electro-hydraulic actuator design. This design offers several key advantages:

1. Electro-Hydraulic Operation: This actuator uses an electrical signal to modulate a hydraulic system, which then generates the mechanical force. This allows for very high force/torque output from a relatively compact unit, as hydraulics provide excellent power density and stiffness. These characteristics are crucial for stable and rapid control responses in dynamic systems.
2. Rotary Output: Unlike linear actuators, these actuators produce rotational motion. This makes them perfectly suited for operating devices such as butterfly valves, rotary dampers, or any other mechanisms that require angular positioning.
3. Double-Acting: The “Double-Acting” feature means that hydraulic pressure is actively applied to both sides of the actuator’s piston or vane. This enables precise control over movement in both directions (e.g., clockwise and counter-clockwise rotation) and allows the actuator to firmly hold a desired position. This is essential for dynamic control applications that demand constant and accurate adjustments.

Key Features and Benefits (General to V45TS-series Actuators like 9907-1608)

• High Positioning Accuracy: These actuators are engineered for highly accurate and repeatable positioning of control elements. This precision is vital for maintaining stable speed, load, frequency, or other critical process variables in a prime mover.
• Fast Response Time: The electro-hydraulic design ensures quick and precise responses to control signals, enabling dynamic adjustments to fuel or steam flow. This rapid response is critical for managing transient conditions and maintaining stability in high-performance turbomachinery.
• Robust Industrial Design: Built to withstand harsh industrial environments, including significant vibration, wide temperature fluctuations, and potential contaminants, the actuator ensures long-term reliability and reduced maintenance needs.
• High Force/Torque Output: The hydraulic power allows the actuator to generate substantial force or torque. This makes it suitable for operating large control valves or dampers, even against high differential pressures. The “1010” in the model name typically indicates a specific force rating (e.g., 56–112 lbs / 25–50 kg of output force).
• Seamless Integration: These actuators are designed to integrate smoothly with Woodward’s comprehensive range of governors and control systems (such as the MicroNet, 505, and Peak series), forming an optimized, closed-loop control solution. They typically accept standard industrial electrical command signals (e.g., 4–20 mA or voltage signals).

Application Areas

The WOODWARD 9907-1608 actuator is a critical component in applications that demand precise, powerful, and rapid control over fluid flow or mechanical position in heavy-duty machinery. Its primary applications include:

• Gas Turbine Fuel Control: Precisely positioning fuel gas or liquid fuel valves to regulate fuel flow to the turbine, directly controlling the turbine’s speed, power output, and exhaust temperature.
• Steam Turbine Valve Control: Actuating steam admission valves, extraction valves, or other critical steam path components to manage turbine speed, generated power, or process steam demands.
• Large Engine Fuel/Air Control: Controlling fuel racks, throttle bodies, or air dampers on large diesel or gas engines for speed, load, and emissions control.
• Compressor Control: Operating critical valves like anti-surge valves or recycle valves in large industrial compressors to maintain stable operation and prevent costly surge conditions.
• Power Plant Auxiliary Control: Controlling dampers in boiler systems, exhaust stacks, or other large air/gas flow paths.
• Other Process Industries: Any large-scale industrial process requiring highly accurate and powerful modulation of fluid flow or mechanical position, especially where the actuator is subjected to demanding operational conditions.

Related Products & Systems

The WOODWARD 9907-1608 actuator doesn’t operate in isolation; it’s an integrated part of a larger, sophisticated control architecture:

• Woodward Governors and Control Systems: These electronic controllers (e.g., 505, MicroNet Plus, Peak series, or specialized turbine/engine control systems like the 2301A/D/E series) serve as the “brain.” They receive sensor feedback, execute complex control algorithms, and send the precise electrical command signal to the 9907-1608.
• Control Valves or Dampers: These are the actual mechanical devices that the actuator directly connects to and manipulates. They are the physical elements that modulate fuel, steam, or air flow.
• Hydraulic Power Units (HPUs): As an electro-hydraulic actuator, a dedicated HPU is necessary to provide the pressurized hydraulic fluid that powers the actuator’s mechanical movement.
• Position Feedback Devices: Actuators often include or are paired with position feedback sensors (e.g., LVDTs, potentiometers) that send the actuator’s actual position back to the controller. This allows for closed-loop control and verification of movement.
