The Genie 31528GT is a genuine OEM Relief Valve, 1600 PSI designed for Genie Z-series articulating boom lifts. As a direct OEM replacement, this valve is built to the same specification as the original component installed at the factory, ensuring correct pressure regulation across the hydraulic system. This part is confirmed to fit the Z-34/22 IC, Z-60/34, Z-30/20 N, Z-34/22 N, Z-34/22 DC, Z-34 IC, and Z-30/20N RJ. Sourcing a genuine Genie part means you can be confident the relief valve will perform exactly as intended — protecting your hydraulic circuit and keeping your boom operating within its designed pressure limits.
Key Features
- Genuine OEM Pressure Calibration — Factory-set to 1600 PSI, matching the original hydraulic system specification for consistent, accurate pressure relief without manual adjustment.
- Direct Hydraulic System Replacement — Engineered to install directly in place of the original valve with correct port sizing and thread specification for a clean swap.
- Broad Z-Series Compatibility — Fits multiple Genie articulating boom variants including the Z-34/22 IC, Z-60/34, Z-30/20 N, Z-34/22 N, Z-34/22 DC, Z-34 IC, and Z-30/20N RJ.
- Hydraulic Circuit Protection — Maintains correct system pressure to prevent component damage caused by over-pressurization, helping the boom's hydraulic actuators operate within their rated range.
- Safety-Critical Component — On articulating aerial booms, a correctly functioning relief valve is essential for controlled movement and safe load handling at height. A failed or out-of-spec valve can result in erratic boom behavior or system overpressure.
A hydraulic relief valve acts as a pressure safety mechanism within the machine's hydraulic circuit. When system pressure reaches the valve's set point — in this case 1600 PSI — the valve opens to divert excess fluid back to the reservoir, preventing damage to pumps, cylinders, hoses, and other hydraulic components. On an articulating boom lift, precise pressure regulation is critical for smooth, controlled boom movement; a worn or stuck relief valve can cause sluggish operation, system overpressure, or unpredictable boom response during use.
