Detailed content
- Supply Pressure: 2413–10 342 kPa (350–1500 psig)
- Maximum Bypass Pressure: 345 kPa (50 psig)
- Flow Accuracy: 5.0% of point or 0.5% of maximum flow
- Filtration: 10 μm nominal, 20 μm absolute
- Temperature Range: 0–66 °C (32–150 °F)
- Material Composition: Stainless steel primary construction; replaceable hardened stainless-steel sleeve; ceramic on metering valve and regulator parts
- Structural Features: Variable-area-metering valve; single-stage throttling delta-P regulator piston
- Working Principle: Actuator-controlled metering plunger sets port opening; delta-P regulator maintains constant differential pressure across metering ports so flow remains unaffected by variations in valve inlet or discharge pressures
- Applications: Industrial gas turbine NOx reduction; water injection control; compatible with Woodward EM Digital Driver or 24 V DVP
- Installation Requirements: Install per Woodward 3151A outline drawings; ensure water supply meets filtration specification
- Usage Notes: Do not operate beyond rated pressure/temperature limits; proper ESD handling required; unauthorized modification voids warranty and certifications
