Product Overview
The Woodward 1751ES / 1700-4138 Fuel Shutoff Solenoid is a precision-engineered electromechanical actuator designed for positive fuel control in industrial diesel engines, gas turbines, and generator set applications. Manufactured by Woodward, a global leader in energy control and optimization solutions, this solenoid functions as a critical safety and shutdown device within engine management systems. When de-energized, the solenoid immediately drives the fuel rack or shutoff lever to the closed position, cutting fuel delivery and bringing the prime mover to a safe, controlled stop. The 1751ES series is widely deployed in power generation, oil and gas, and marine propulsion systems where fail-safe fuel interruption is mandatory for operational safety and regulatory compliance.

Engineering Features & Advantages
- Fail-Safe Shutdown Logic: Spring-return mechanism ensures immediate fuel cutoff upon loss of electrical signal, providing critical overspeed and emergency stop protection.
- Precision Coil Winding: High-tolerance solenoid coil delivers consistent pull-in force and rapid response times across the full operating temperature range.
- Industrial Reliability: Built for continuous operation under severe industrial conditions including high vibration, thermal cycling, and contaminated environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Woodward 1751ES and 1700-4138 OEM specifications for drop-in installation.
- Corrosion-Resistant Construction: Robust housing and plating protect internal components against moisture, fuel exposure, and industrial contaminants.
Typical Industrial Applications
This Woodward fuel shutoff solenoid is commonly specified for diesel generator sets and standby power systems, gas turbine fuel control skids, marine propulsion and auxiliary engines, and oil and gas reciprocating compressor packages. It is also widely used in heavy-duty off-highway equipment and industrial engine retrofits where reliable, fail-safe fuel interruption is required for safety compliance and operational integrity.
