Detailed content
- Flow Rate: Minimum 3.8 L/min (1 US gal/min); Maximum 250 L/min (66 US gal/min)
- Supply Pressure: 2413 to 10 342 kPa (350 to 1500 psig)
- Flow Accuracy: 5.0% of point or 0.5% of maximum flow
- Filtration: 10 μm nominal, 20 μm absolute
- Temperature Range: 0 °C (32 °F) to 66 °C (150 °F)
- Material Composition: Stainless steel body; hardened stainless-steel replaceable cavitation sleeve; ceramic metering and regulator components
- Structural Features: Contoured-port variable-area metering sleeve; single-stage delta-P regulator piston
- Working Principle: Metering plunger position (set by actuator) determines port opening; delta-P regulator senses and controls pressure drop across metering ports so flow is unaffected by variations in valve inlet or discharge pressures
- Applications: Gas turbine water/steam injection for NOx reduction; works with Woodward EM Digital Driver or 24 V DVP
- Installation Requirements: Install per Woodward 3151A installation documentation; connect to high-pressure centrifugal pump with proper pre-filtration
- Usage Notes: Unauthorized use outside specified limits constitutes misuse and voids warranty; follow ESD precautions when handling electronic controls; verify latest manual revision before service
