The Genie 77410GT is a genuine OEM Counterbalance Valve, 1500 PSI designed for Genie S series telescopic boom lifts and Z series articulating boom lifts. As a direct OEM replacement sourced from Genie, this valve is built to the exact pressure rating and dimensional specification required by the hydraulic systems found on these machines. It fits a broad range of models including the S-40 XC, S-45 TRAX, Z-45/25J Bi-Energy, Z-60/37 DC, Z-60/37 FE Hybrid, Z-62/40, and many additional S and Z series variants — cross-reference part number 77410GT against your parts manual to confirm fitment for your specific machine. Installing the correct counterbalance valve is critical to safe and controlled boom movement, making this a part where OEM specification matters most.
Key Features
- Rated to OEM Pressure Spec — Calibrated to 1500 PSI, matching the hydraulic circuit requirements of Genie S and Z series booms for controlled load-holding performance.
- Genuine OEM Component — Sourced directly from Genie, this valve carries the same part specifications as the original — no guesswork on porting, thread size, or cracking pressure.
- Wide Boom Lift Compatibility — Fits Genie S series telescopic booms (S-40 XC, S-45 XC, S-40 TRAX, S-45 HF and more) and Z series articulating booms (Z-45/25J, Z-60/37 DC, Z-62/40, Z-45/25 IC, and additional variants).
- Controlled Boom Descent — A properly functioning counterbalance valve prevents uncontrolled boom drift or drop under load, maintaining smooth, predictable cylinder movement during all boom operations.
- Critical Safety Component — On aerial boom lifts, the counterbalance valve is a primary load-holding device. A failed or incorrectly rated valve can result in uncontrolled platform movement — replacing it with the correct OEM-spec part is essential for safe operation.
A counterbalance valve is a hydraulic safety and control component that holds a load in position and prevents a cylinder from moving faster than the flow of fluid being supplied to it. On boom lifts, it is installed in the hydraulic circuit for the lift and extension cylinders, ensuring the boom cannot drift, drop, or overrun when the operator stops a movement or when an external load is applied to the platform. When this valve fails — through wear, contamination, or pressure drift — the result can be erratic boom movement, slow response, or an inability to hold the platform at elevation. Replacing it with a correctly rated valve, such as this 1500 PSI genuine OEM unit, restores the hydraulic circuit to its intended operating behavior.
