The Genie 45489GT is a genuine OEM Relief Valve, 3000 PSI built for Genie S-60, S-65, and Z-45/22 MP boom lifts. As a direct OEM replacement, this valve is manufactured to the exact pressure rating and dimensional specifications of the original part. Cross-reference part number 45489GT against your machine's parts manual to confirm it is the correct valve for your serial number and configuration before ordering.
Key Features
- Factory-Rated Pressure Specification — Built to an exact 3000 PSI rating, matching the original valve's calibration and ensuring the hydraulic circuit is protected at the correct threshold.
- Genuine OEM Construction — Manufactured to Genie's original material and tolerance standards, so this valve seats, seals, and operates exactly as the unit it replaces.
- Direct-Fit Replacement — Designed to install in the same position as the original, with no port modifications or adapter fittings required.
- Verified Fitment — Confirmed for Genie S-60 and S-65 telescopic boom lifts and the Z-45/22 MP articulating boom lift.
- System Pressure Protection — A correctly functioning relief valve limits hydraulic pressure to its set point, preventing component damage from pressure spikes. A failed or miscalibrated valve can cause erratic boom movement or system overpressure.
- Operational Safety — On aerial boom lifts, proper pressure relief is critical to controlled, predictable movement of boom functions. An OEM-rated valve ensures the machine responds within its designed pressure envelope.
A relief valve is a pressure-control device that opens to divert fluid when system pressure reaches its set limit — in this case, 3000 PSI — protecting downstream components from damage caused by excess pressure. On boom lifts, relief valves govern the hydraulic circuits that control boom extension, lift, and rotation, so a failed or out-of-spec valve can result in sluggish response, uncontrolled movement, or component failure. Replacing a worn or leaking valve with the correct OEM-rated part restores proper pressure control and keeps boom functions operating within their designed parameters.
