3930233 SA-4335-12 12V Fuel Shutdown Solenoid Valve - SINOCMP Stop Solenoid for Cummins 6BT & 6CT Engine, 3 Month Warranty

Product SpecificationsPart Numbers: 3930233, SA-4335-12, 3923680Voltage: 12V DC (nominal operating range: 10.5V - 14.5V)Solenoid Type: Pull-type stop solenoid (spring return to extended position)Duty Cycle: Intermittent (energized when engine runs, de-energized at shutdown)Terminal Type: Single wire (ground through mounting bracket)Mounting: 2-bolt flange mountPlunger Action: Energized = retracted / De-energized = extended (spring return)Material: Steel body with composite plastic coil coverCompatible with Cummins EnginesFor Cummins 6BT 5.9L (6-cylinder, mechanical injection, 1989-1998 typical)For Cummins 6CT 8.3L (6-cylinder, mechanical injection)Also fits for Hyundai R300 excavators with these for Cummins enginesStop Solenoid Function for Cummins PT PumpsNormal Operation (Key ON): 12V power energizes the 3930233 solenoid coil. Magnetic field retracts the plunger (pulls inward). Fuel rack moves to RUN position for Cummins PT pump. Engine runs.Shutdown (Key OFF): Power removed from SA-4335-12 solenoid. Internal spring extends the plunger (pushes outward). Fuel rack moves to STOP position. Fuel flow blocked for Cummins 6BT engine. Engine stops within 3 seconds.Safety Feature: Prevents engine runaway by cutting fuel when key is turned off or electrical power fails on your diesel engine.

• 🔋 Voltage Verification - SA-4335-12 fuel shutoff solenoid operates on 12V DC only. Before ordering this 12V stop solenoid for Cummins engine, verify your equipment uses a 12V electrical system. The 3930233 solenoid requires 12V for proper plunger retraction.
• 📋 Part Number Cross-Reference - 3930233 fuel solenoid replaces for Cummins numbers 3930233, SA-4335-12, and 3923680. The 12V stop solenoid is original equipment for Cummins 6BT and 6CT mechanical diesel engines. Verify your old solenoid matches one of these numbers before ordering this SA-4335-12 replacement.
• 🚜 For Cummins Engine Compatibility - SA-4335-12 shutoff solenoid fits for Cummins 6BT 5.9L and 6CT 8.3L diesel engines. Also compatible with Hyundai R300 excavators powered by these for Cummins engines. The 12V solenoid mounts on the PT (Pressure-Time) fuel pump or injection pump. Not for common rail or electronically controlled for Cummins engines.
• ⛽ Engine Shutdown Function - 3930233 fuel stop solenoid cuts fuel supply when de-energized. When you turn off the ignition for Cummins 6BT engine, power is removed from the 12V solenoid. The spring-loaded plunger extends to block the fuel rack, stopping the engine within 3 seconds. The SA-4335-12 solenoid energizes (plunger retracts) when the engine runs. A failed 3930233 solenoid for Cummins 6CT causes no-start or engine-run-after-key-off conditions.
• 🔧 Installation Note - Installing SA-4335-12 12V stop solenoid requires basic hand tools. The 3930233 solenoid mounts with two bolts for Cummins PT pump or injection pump. Single wire terminal - body grounds through mounting bracket. Test solenoid operation by applying 12V - plunger should retract with an audible click on your diesel engine. Do not run engine until you verify proper plunger movement for Cummins 6BT.
