Description
Proportional Directional Valve 107788GT / 107788 (3-Position 4-Way) – Optimized Product Page Content
🔹 Product Overview
The Proportional Directional Valve with Genie part numbers 107788GT and 107788 is a high-specification, critical electro-hydraulic component used in the main control systems of various Genie Aerial Work Platforms (AWP). This valve features a 3-Position, 4-Way (3/4-Way) configuration, making it suitable for controlling a double-acting cylinder or bi-directional motor. Crucially, it is proportional, meaning it not only controls the direction of flow but also precisely modulates the flow rate (and thus the speed) in direct response to a variable electrical signal from the machine’s controller (e.g., joystick input).
This valve is essential for achieving smooth, precise, and variable-speed movement in critical, primary functions such as main lift, lower, or telescope. The center position is typically used for a defined holding state. The part number 107788GT is the necessary replacement for addressing issues such as a failure to achieve fine speed control, erratic/jerky movement, loss of one direction of travel, or inability to hold position due to internal spool or coil failure.
🔹 Key Features & Benefits
✅ Proportional Control: Enables smooth, variable speed/force control in both directions, proportional to the electrical input.
✅ 3-Position 4-Way (3/4W): Standard configuration for controlling bi-directional functions with a defined center/hold state.
✅ High Control Fidelity: Essential for main boom and drive functions that require continuous speed modulation and smooth start/stop.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 107788GT and 107788.
