Woodward 8290-195 Flo‐Tech Speed Control

Product Overview

The Woodward 8290-195 is a Flo-Tech Speed Control designed for precise mechanical-hydraulic governor performance in engine applications. It delivers accurate engine speed regulation through a 24VDC-powered control system that interfaces with fuel metering valves and actuators. The Flo-Tech series is particularly suited for engines requiring flow-based fuel control with pre-programmed flow curves for optimal combustion efficiency.

FAQ

Q: Is the 8290-195 still available?
A: No. Woodward has discontinued this model. Limited stock may be available from surplus suppliers, but the recommended replacement is 8245-020.

Q: What is the recommended replacement?
A: Woodward recommends 8245-020 (75mm F-series based ITB). The old Flo-tech flow curve is pre-programmed, and a cable harness is included for easy migration.

Q: What is Flo-Tech technology?
A: Flo-Tech is Woodward's flow-based fuel control technology that uses pre-programmed flow curves to optimize fuel delivery for engine combustion efficiency.

Q: What is the control output signal?
A: 0–20 mA analog current signal for actuator positioning.

Q: Can I use the 8290-195 with non-Woodward actuators?
A: The 8290-195 is designed for Woodward Flo-tech fuel metering valves. For other actuators, verify compatibility or consider the replacement 8245-020.

Model Selection Tips

• 8290-195 = Discontinued Flo-Tech Speed Control (24VDC)
• Recommended replacement: 8245-020 (75mm F-series based ITB with pre-programmed flow curve)
• For new installations, order 8245-020 directly instead of 8290-195
• For existing systems, migration kit includes cable harness for plug-and-play replacement
• Verify engine fuel system type (Flo-tech valve) before ordering replacement
• For alternative speed control technologies, consider 9905-792 (ProAct Digital) or 9907-164 (505E)
