The Genie 107738GT is a genuine OEM Differential Sensing Valve designed for the Z-135/70 and ZX-135/70 articulating boom lifts. Sourced directly from Genie, this valve meets the exact engineering standards specified for these large-platform machines, ensuring the hydraulic system performs as intended. Cross-reference part number 107738GT against your parts manual to confirm this is the correct valve for your unit before ordering. For operators running Z-135/70 or ZX-135/70 booms, using the correct OEM-specified component is essential to maintaining the precise hydraulic control these machines demand at height.
Key Features
- Genuine OEM Hydraulic Precision — Built to exact Genie pressure-sensing tolerances, this valve maintains the differential flow balance that large articulating booms rely on for smooth, controlled movements.
- Direct Drop-In Replacement — Engineered to match the original valve's port configuration and mounting interface, this part installs directly into the hydraulic circuit without adaptation.
- Confirmed Fitment for Z-135/70 and ZX-135/70 — Verified compatibility with both the Z-135/70 and ZX-135/70 articulating boom lift variants, including the ZX extended-reach configuration.
- Maintains Hydraulic System Balance — A correctly functioning differential sensing valve keeps hydraulic pressure equalized across circuits, enabling fluid, proportional boom movement at every elevation and extension angle.
- Critical Safety Component for Aerial Operations — On large articulating booms operating at extreme heights, proper differential pressure sensing is directly tied to controlled platform movement and safe aerial operation. This genuine OEM part preserves that integrity.
A differential sensing valve monitors and balances pressure differences between hydraulic circuits within the boom's control system. By detecting these pressure differentials, it regulates flow so that simultaneous boom functions — such as lifting and extending — remain smooth and proportional rather than erratic or uncontrolled. When this valve fails or wears, operators may notice sluggish response, uneven boom movement, or loss of hydraulic function priority, all of which compromise safe, efficient operation of the machine. Replacing it promptly with the correct OEM-specified component restores the precise hydraulic behavior these large articulating booms require.
