The Genie 107739GT is a genuine OEM Directional Valve designed for Z-135/70 and ZX-135/70 articulating boom lifts. Sourced directly from Genie, this valve matches the original hydraulic specification for these large-platform booms, ensuring correct porting, flow rating, and mechanical interface with no guesswork. Cross-reference part number 107739GT against your parts manual to confirm fitment before ordering. When a directional valve begins to fail on a high-reach machine like the Z-135/70 or ZX-135/70, the consequences show up fast — sluggish or unresponsive boom movement, hydraulic drift, and compromised operator control at height. Replacing it with a genuine OEM component restores the hydraulic response and positional accuracy these machines demand.
Key Features
- Genuine OEM Hydraulic Specification — Matched to the original valve body dimensions, port configuration, and flow characteristics of the 107739GT, ensuring the hydraulic circuit performs exactly as engineered.
- Direct-Fit Replacement — Mounts to the existing hydraulic manifold on Z-135/70 and ZX-135/70 booms using the original hardware and port connections, simplifying installation for your service team.
- Confirmed Fitment for Z-135/70 and ZX-135/70 — Engineered specifically for these large articulating boom platforms, eliminating compatibility uncertainty on critical hydraulic components.
- Restores Precise Boom Control — A functioning directional valve routes hydraulic flow accurately to each actuator, maintaining smooth, responsive movement across the full range of boom articulation.
- Critical Safety Component — On high-reach articulating booms, directional valve integrity directly affects the operator's ability to position and hold the platform safely; a genuine replacement preserves that control authority.
A directional valve controls which hydraulic circuit receives pressurized fluid and in which direction that fluid flows, acting as the routing core for boom and platform movement commands. On an articulating boom lift like the Z-135/70 or ZX-135/70, the valve responds to operator inputs and directs fluid to the appropriate cylinders to raise, lower, extend, or swing the boom. When the valve wears internally or begins to bypass fluid, operators experience sluggish response, unintended drift, or complete loss of a function — any of which can be a serious operational hazard at the working heights these machines are built to reach.
