Woodward Industrial Turbine Fuel Control Valves

Water Control Valves for Gas Turbines

3151A Water Valve/EML 100 Actuator 

Woodward’s 3151A Water Valve with EML100 actuator controls water flow to reduce overall emissions of aeroderivative gas turbines.

The 3151A Water Valve is intended for use with high-pressure, centrifugal-type pumps, and provides controlled bypass flow for pump stability and heat balance considerations. Critical internal parts are constructed of ceramic materials to prevent galling and resist erosion and cavitation in areas subject to high-velocity water streams.

The EML100 Actuator consists of a high performance, brushless servomotor and a precision planetary gearbox with two shaft position resolvers.

The 3151A/EML100 assembly is designed to be used with either the Woodward EM Digital Driver or the more recent Woodward DVP driver. The drivers are calibrated so that the water valve closely follows the fuel flow schedule to prevent unwanted water injection during turbine load swings.
