Directional Control Valve 84109GT / 84109 (#10 SAE, 3-Position) – Optimized Product Page Content

🔹 Product Overview
The Directional Control Valve with Genie part numbers 84109GT and 84109 is a standard, high-flow hydraulic component used in the manifold blocks of various Genie Aerial Work Platforms (AWP). This valve is configured as a 3-Position valve, meaning it has three distinct operating modes (e.g., Extend, Hold/Neutral, Retract). The #10 SAE designation refers to the industry-standard size of the cartridge and its sealing port, indicating it is typically used for medium-to-high flow applications.
This valve is essential for controlling a double-acting cylinder or motor (bi-directional movement) and includes a crucial neutral position for holding the function steady. The part number 84109GT is the necessary replacement for addressing issues such as failure of the function to move in one or both directions, the inability to hold position (drift) in neutral, or erratic shifting between positions.
🔹 Key Features & Benefits
✅ 3-Position Control: Provides precise control over bi-directional movement with a defined center/neutral holding position.
✅ #10 SAE Standard: Indicates a medium-to-high flow capacity, suitable for main lift or travel functions.
✅ Versatile Application: Used for critical hydraulic functions requiring three modes (forward, neutral, reverse) of operation.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 84109GT and 84109.
