Woodward 8915-123

Product Overview:​ 8915-123 is a high-performance digital microprocessor-based controller module manufactured by Woodward. It is primarily used for displaying and controlling the operating status and parameters of steam turbines. Its core function includes controlling turbine start-up, shutdown, acceleration, and deceleration operations by driving single or double extraction-stage actuators to operate steam inlet valves, thereby achieving speed and load control of turbine compressors. It is part of the Woodward 505/505E turbine control platform family.

Woodward 8915-1152

Product Name:​ 3103 Series Stainless Steel Gas Valve with EM35MR All-Electric Actuator Package
Product Overview:​ 8915-1152 is a fully matched, factory-calibrated actuator-and-valve combination unit manufactured by Woodward. It integrates a 3103-series stainless steel gas valve with an EM35MR all-electric actuator, driven by a brushless DC motor with planetary gear reduction. The package is designed to eliminate hydraulic oil supply entirely, removing hydraulic contamination and maintenance overhead from gas turbine fuel control.

Woodward 8915-708

Product Name
3103 Gas Valve with TM-55 Actuator (3103/TM55 configuration).
Product Introduction
The 8915-708 is a Woodward configured package of the 3103 stainless steel rotary gas metering valve with a TM-55 electro-hydraulic integrating actuator, supplied as a matched and factory-calibrated valve/actuator assembly for industrial gas turbine fuel metering from light-off to full load.

Woodward 8915-703

Product Name
3103 Gas Valve with EM35 Electric Actuator (3103/EM35 configuration).
Product Introduction
The 8915-703 is a Woodward configured package of the 3103 stainless steel rotary gas metering valve integrated with an EM35 electric actuator. Unlike the TM-55 hydraulic version, this configuration uses an electrically powered actuator, making it suitable for installations where a hydraulic power supply is not available or desired, while maintaining precise fuel metering for industrial gas turbine applications.
