WOODWARD
MODEL: 2001-12E2U1B1S1A
FUEL SHUT OFF STOP SOLENOID VALVE
P/N.: 2000-4505
VDC 12
PATENT# 4,407,517
The Woodward 2001-12E2U1B1S1A is a 12 VDC fuel shutoff stop solenoid valve designed to interrupt fuel supply to a diesel engine on command, providing a rapid and reliable engine stop function. As a core component within a marine control system, this solenoid valve plays a critical safety role — ensuring that engines can be shut down promptly in response to automation signals, manual override commands, or emergency shutdown triggers. Its dependable actuation characteristics make it well suited to the demanding operational environment found aboard commercial and working vessels.
Key Features
✓ Operates at 12 VDC, providing a positive fuel shutoff action to halt engine operation when energised or de-energised, depending on circuit configuration.
✓ Part number 2000-4505 identifies this unit within the Woodward product range; system and installation compatibility should be confirmed against vessel-specific documentation and nameplate data.
✓ Designed for integration with Woodward governor and engine control systems, supporting automated shutdown sequences typical of marine diesel engine management architectures.
✓ Compact solenoid valve construction suits installation in engine room environments where space and vibration resistance are important considerations; exact mounting requirements are subject to confirmation against original installation drawings.
✓ Manufactured under Woodward Patent No. 4,407,517, reflecting established engineering design principles for fuel control and engine shutdown applications.
Marine Applications
✓ Main propulsion diesel engines aboard cargo vessels, bulk carriers, and tankers requiring automated or remote fuel shutoff capability.
✓ Auxiliary generator sets and emergency generator installations where reliable engine stop functions are mandated by class and flag state requirements.
✓ Offshore support vessels and platform supply vessels utilising Woodward governor systems for engine speed and fuel management.
✓ Tugboats, fishing vessels, and workboats with 12 VDC electrical systems integrating Woodward fuel control components.
✓ Retrofit and replacement applications on any vessel where an existing Woodward fuel shutoff solenoid valve requires like-for-like substitution within the engine control system.
Why Marine Engineers Choose
Woodward has a long-established reputation in marine governor and fuel control technology, and components such as this solenoid valve are valued for their consistent actuation performance, robust construction, and compatibility with Woodward engine management architectures — reducing integration risk during replacement or overhaul.
Ideal For
Commercial cargo vessels, tankers, bulk carriers, offshore support and supply vessels, tugboats, fishing vessels, and any marine operator running Woodward-equipped diesel engines that require a proven 12 VDC fuel shutoff stop solenoid valve.
