The Genie 122302GT is a genuine OEM Relief Valve, 270 PSI designed for a wide range of Genie telescopic boom lifts, articulating boom lifts, and GS scissor lifts. As a direct OEM replacement, this valve is built to the same specifications as the part that left the factory, ensuring correct pressure regulation for the hydraulic circuit it serves. Compatible machines include S-series telescopic booms such as the S-40, S-60 XC, S-80, S-85, S-100, S-105, S-120, and S-125, GS scissor lifts including the GS-3384, GS-3390, GS-4390, and GS-5390, and Z-series articulating booms including the Z-60/34 and Z-80/60. Cross-reference part number 122302GT against your machine's parts manual to confirm this is the correct valve for your unit before ordering.
Key Features
- Factory-Rated Pressure Setting — Set to the exact 270 PSI specification, this relief valve maintains the correct hydraulic pressure threshold the machine is engineered to operate within.
- Genuine OEM Quality — Sourced directly from Genie, this component meets the same material and dimensional standards as the original, with no guesswork on tolerances or seat geometry.
- Direct OEM Replacement — Designed to install in place of the original valve with no adaptation, using the same port configuration and thread spec as the factory-fitted component.
- Broad Genie Fitment — Fits a wide range of Genie S-series telescopic booms, GS-series scissor lifts, and Z-series articulating booms — one part covering multiple equipment families in your fleet.
- Protects the Hydraulic Circuit — A correctly functioning relief valve prevents overpressure conditions that can damage components throughout the circuit. A failed or out-of-spec valve can result in sluggish operation, component stress, or system failure.
- Operational Safety — On aerial work platforms, accurate pressure control is directly tied to safe lift and boom function. Using an OEM-spec valve ensures the relief point is not compromised by an imprecise replacement.
A relief valve is a pressure-control component in a hydraulic circuit. It acts as a safety boundary, opening to redirect fluid when pressure in the circuit exceeds a set threshold — in this case, 270 PSI — and closing again once pressure drops back to a safe level. This prevents overpressure from building up and damaging pumps, cylinders, hoses, and other hydraulic components downstream. When a relief valve sticks open, the circuit loses pressure and the machine may become slow or unable to lift; when it sticks closed or is set too high, excessive pressure can cause component damage or unsafe operating conditions. Replacing a worn or failed valve with the correct OEM part restores proper pressure regulation and keeps the machine operating within its designed parameters.
