Stop Shutdown Solenoid Valve 77402GT – Optimized Product Page Content

Genie Engine Stop Solenoid Valve 77402GT

🔹 Product Overview

The Stop Shutdown Solenoid Valve with Genie Part Number 77402GT (also cross-referenced as 77402) is a highly critical electro-hydraulic component used in the engine management system of large Genie Articulating and Telescopic Boom Lifts (S-Series) and Rough Terrain Scissor Lifts (GS-Series).

This solenoid valve controls the flow of oil or hydraulic pressure to the engine’s mechanical shutdown mechanism (e.g., controlling the flow to the injection pump rack or a hydraulic actuator). Its primary role is to ensure a positive and immediate engine stop when the ignition is turned off or an emergency stop is activated.

When this solenoid valve fails, the engine may either fail to start or, more dangerously, fail to shut down, leading to a hazardous run-on condition. Replacing the failed unit with the 77402GT restores reliable engine shutdown control, which is essential for operator safety and machine compliance.

🔹 Key Features & Benefits

✅ Engine Shutdown Control: Critical solenoid valve that electrically manages the hydraulic or oil flow necessary for engine shutdown actuation.
✅ Wide Model Compatibility: Used extensively on high-reach Genie Boom Lifts (S-40 to S-85) and large Rough Terrain Scissor Lifts (GS-3390 to GS-5390).
✅ Restores Safe Shutdown: Ensures the engine stops immediately upon command (ignition off or E-stop), eliminating run-on conditions.
✅ Durable Construction: Built to withstand the harsh operating environment and vibration common in large diesel equipment.
✅ Direct Replacement: High-quality aftermarket or genuine OEM equivalent for Genie Part Number 77402GT.
