Detailed content
- Supply Pressure: 2413–10 342 kPa (350–1500 psig)
- Flow Accuracy: 5.0% of point or 0.5% of maximum flow (whichever is greater)
- Filtration: 10 μm nominal, 20 μm absolute
- Temperature Range: 0–66 °C (32–150 °F)
- Material Composition: Stainless steel primary construction; hardened stainless-steel replaceable sleeve; ceramic metering and regulator components
- Structural Features: Variable-area-metered bypass valve with delta-P regulating piston
- Working Principle: Actuator-driven metering plunger controls port opening; delta-P regulator maintains constant pressure differential across metering ports for flow stability
- Applications: Industrial gas turbine NOx reduction systems; water/steam injection control
- Installation Requirements: Follow Woodward’s 3151A Water Valve installation drawings; ensure water supply filtration meets specification before connection
- Usage Notes: Do not operate beyond rated pressure and temperature limits; proper ESD handling required for associated electronic driver; unauthorized modification will void product certification and warranty
