Woodward 8915-884
Woodward 8915-884 is a 3151A Water Valve in Woodward’s 8900-series turbine valve lineup, used for gas turbine water injection NOx reduction.
- Product Type: 3151A Water Valve
- Core Function: Metered water bypass flow for gas turbine combustion chamber water injection
- Medium: Water
Detailed content
- Flow Rate: 3.8–250 L/min (1–66 US gal/min)
- 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 cavitation sleeve; ceramic on metering valve and regulator parts
- Structural Features: Variable-area-metering valve; single-stage throttling delta-P regulator piston; sleeve can be rotated in quarter-turn increments or replaced
- Working Principle: The actuator-controlled metering plunger determines port opening; the delta-P regulator senses and maintains differential pressure across metering ports so flow is unaffected by variations in valve inlet or discharge pressures
- Applications: Industrial gas turbine water/steam injection for NOx reduction; compatible with Woodward EM Digital Driver or 24 V DVP
- Installation Requirements: Install per Woodward 3151A outline drawings; ensure water supply pre-filtration to 10 μm nominal / 20 μm absolute
- Usage Notes: Do not operate beyond rated pressure and temperature limits; proper ESD handling required when working with associated electronic controls; unauthorized modifications void warranty and invalidate product certifications; verify latest manual revision on Woodward website before installation or service
