The Genie 77491GT is a genuine OEM Flow Regulator Valve, 2.3 GPM, designed for Z-62/40 and Z-80/60 articulating boom lifts. As a factory-sourced component, this valve delivers the exact flow specification engineered for these machines, ensuring the hydraulic system performs precisely as intended. Cross-reference part number 77491GT against your parts manual to confirm fitment before ordering.
Key Features
- Exact OEM Flow Rating — Rated at 2.3 GPM to match the original hydraulic design, this valve regulates fluid delivery with the precision these boom lifts require — no guesswork on flow calibration.
- Genuine Genie OEM Part — Sourced directly from Genie, this component meets the same material and dimensional standards as the part installed at the factory, dropping in where the original valve seats.
- Confirmed Fitment for Z-Series Booms — Fits Genie Z-62/40 and Z-80/60 articulating boom lifts, two of the larger Z-series models commonly found on heavy-access commercial and industrial job sites.
- Consistent Hydraulic Function — A correctly functioning flow regulator keeps boom movement smooth and controlled. A worn or out-of-spec valve can cause erratic motion, sluggish response, or uneven platform travel.
- Operational Safety on Elevated Work Platforms — On articulating boom lifts, controlled hydraulic flow is directly tied to safe platform positioning. Replacing a degraded valve with the correct OEM part restores that predictable, safe operation.
A flow regulator valve controls the rate at which hydraulic fluid moves through a circuit, limiting flow to a set volume — in this case, 2.3 GPM — regardless of system pressure fluctuations. On articulating boom lifts like the Z-62/40 and Z-80/60, this type of valve governs the speed and smoothness of boom and platform movements, preventing functions from operating too fast under varying load conditions. When the valve degrades or fails, operators may notice uneven boom travel, loss of controlled movement, or hydraulic functions that respond inconsistently — all signs that the regulator is no longer holding its rated flow.
