Category: Woodward

Rugged and precise fuel control and shutoff valves for large, heavy-duty gas

turbines with single or multiple combustion manifold systems.

Available in electric or hydraulic models.

Features & Benefits

• Ultra-low pressure drop valve body design reduces gas compression operating costs

• Electric actuator options eliminate the need for high-pressure hydraulic fluid,

which improves safety and eliminates downtime caused by hydraulic fluid varnishing clogging servo

valves

• Onboard diagnostics to provide advance notification of potential operating problems

Product Variants

• LESV – Large Electric SonicFlo Valve

• Electric Rotary Pressure and Flow Control Valve

• Hydraulic Gas Control Valve

• Hydraulic Stop/Ratio Valve

The 3103 gas valve is a rotary sleeve-and-shoe type-throttling valve.

Valve position feedback to the actuator driver is accomplished using a high accuracy resolver.

The EM35MR actuator is designed for use with the DVP (Digital Valve Positioner).

Features and Benefits

• Design of the valve is to be corrosion resistant and self-cleaning, allowing it to

operate in sour gas environments (high sulfur content gas) that can cause problems for other valves

• The EM35MR actuator is all electric, reducing hydraulic contamination and maintenance problems

• The DVP uses the latest in Woodward control architecture, robust controller to provide high-speed

precise valve control

Cost-effective design

The 505DR is a G-efficient redundant turbine controller.

It consists of a turbine controller, system sequencer, operator control panel and first-out indicator.

The design minimises external equipment and wiring for easy troubleshooting.

Like the 505XT, the 505DR can be fully configured in the field

(under password control by knowledgeable personnel) and minor functional

changes can be made while the turbine is running online.

Minor functional changes can be made online while the turbine is running.

Like the MicroNet Plus, the 505XT system designates one controller

as the System Controller (Syscon), actively controlling the fan.

The second device is configured as a backup.

The system automatically evaluates the health of the Syscon and initiates a fast switchover in the event of

a failure.

Switchover can also be initiated manually. The system closely synchronises

the Syscon’s software status and memory with the backup,

ensuring that the control output remains stable and does not affect turbine operation (a true ‘bufferless’

switchover).

If the optional HMI version is selected, the display and keypad are redundant

(input from either keypad will command Syscon, and the display can be independently selected to show

different screens.

For example, one screen can display speed and speed settings, and another can display a steam map.

Woodward’s optional RemoteView programme allows remote monitoring from any networked PC.

The programme can be used either with the rear panel mounted version (as the main HMI)

or as an additional remote monitor to the HMI version.

The optional FTM (Field Terminal Module) allows easy multiplexing of

redundant signals and facilitates fast installation and commissioning.
