The Genie 31749GT is a genuine OEM Relief Valve, 1200 PSI designed for the Z-45/22 MP articulating boom lift. Sourced directly from Genie, this part meets the exact pressure rating and dimensional specifications of the original component, ensuring a direct, correct-fit installation into the hydraulic circuit. Verified against part number 31749GT in your Genie parts manual to confirm fitment on the Z-45/22 MP before ordering.
Key Features
- Rated to Spec — Factory-calibrated at 1200 PSI, this valve opens and relieves at the precise pressure threshold the hydraulic system was engineered around — no guesswork, no re-calibration required.
- Genuine OEM Component — Manufactured to Genie's original design tolerances, this relief valve delivers the same material grade, port dimensions, and cracking pressure as the part it replaces.
- Direct Replacement for Z-45/22 MP — Engineered specifically for the Z-45/22 MP articulating boom lift, this valve installs directly into the existing hydraulic circuit without modification.
- Hydraulic System Protection — A correctly functioning relief valve prevents pressure spikes from damaging pumps, cylinders, and control valves — keeping the entire hydraulic system operating within its designed limits.
- Safety-Critical Fitment — On an articulating boom lift, hydraulic pressure control is directly tied to boom movement and platform stability. Installing a correctly rated OEM valve helps maintain the machine's intended operating safety margins.
A relief valve is a pressure-regulating component within the hydraulic system that acts as a safety mechanism against over-pressurization. When hydraulic pressure in the circuit exceeds the set threshold — in this case, 1200 PSI — the valve opens to divert excess fluid back to the reservoir, protecting downstream components such as cylinders, seals, and the hydraulic pump from damage. When a relief valve fails, sticks open, or is set to the wrong pressure, the result can be sluggish boom movement, excessive heat buildup, or loss of hydraulic control — any of which can affect the safe operation of the Z-45/22 MP in the field.
