Woodward 8915-883
Product Name: Woodward 8915-883 — 1907 Large Liquid Valve & Actuator Assembly
Product Description: The 8915-883 is listed in Woodward parts documentation as a 1907 Large Liquid Valve & Actuator assembly for gas turbine liquid fuel metering. Note: Some third-party resellers describe this part generically as a “digital microprocessor controller module for industrial turbines,” but the authoritative Woodward parts catalog identifies it as a 1907 Large Liquid Valve & Actuator. The technical profile below reflects the 1907 valve and actuator assembly configuration.
Detailed content
Technical Specifications:
-
Metered Fuel Flow: 30:1 turndown, maximum 11,340 kg/h (25,000 lb/h)
-
Minimum Fuel Flow: 68 kg/h (150 lb/h)
-
Fuel Inlet Pressure (Maximum): 9,377 kPa (aluminum body) / 17,238 kPa (stainless steel body)
-
Fuel Outlet Pressure (Maximum): 9,032 kPa (aluminum body) / 16,893 kPa (stainless steel body)
-
Differential Pressure: 345 to 827 kPa
-
Fuel Viscosity: 0.5 to 12.0 centistokes
-
Fuel Specific Gravity: 0.77 to 0.91
-
Cleanliness: 20 μm filtration, water ≤0.1%, particulates ≤1.0 mg/L
Fuel Compatibility: Diesels, kerosenes, gasolines, light and heavy distillates, naphtha, gas turbine fuels, fuel oils, biodiesel compatible with FKM elastomers; ultra-low sulfur diesel acceptable with lubricity additives.
Functional Features:
-
Differential pressure regulated constant flow metering
-
Full-range valve positioning via integrated actuator
-
Multiple flow range configurations available
Application Scenarios: Gas turbine liquid fuel control in power generation, oil & gas, petrochemical, and marine industries.
Material Composition: Aluminum or stainless steel valve body; through-hardened stainless steel internals; FKM elastomer seals.
Working Principle: The integrated actuator positions the 1907 valve’s hollow plunger within the ported sleeve. The built-in differential pressure regulator maintains a constant pressure drop across the metering port, delivering fuel flow that remains constant regardless of discharge pressure or inlet flow variations.
Installation Requirements:
-
Install valve square with governor/actuator linkage to prevent binding
-
Allocate actuator output: approximately two-thirds between minimum and maximum fuel positions
-
Split remaining travel between max and min ends for positive shutdown and maximum fuel assurance
-
Use shielded wiring for electrical connections
-
Follow Woodward outline drawings for dimensional compliance
Usage Precautions:
-
Maintain fuel filtration at 20 μm absolute or finer
-
Limit water content to 0.1% by volume; solids/sediment to 1.0 mg per liter
-
Read this entire manual and all other publications pertaining to the work before installing, operating, or servicing
-
Practice all plant and safety instructions and precautions
-
Failure to follow instructions can cause personal injury and/or property damage
