The Genie 45491GT is a genuine OEM Relief Valve, 2000 PSI designed for Genie Z-series articulating boom lifts, including the Z-45/22D, Z-45/22DRT, Z-25/8, Z-20/8, and Z-20/8N. As a direct OEM replacement, this valve is built to the same specification as the original component installed at the factory, ensuring the hydraulic system operates within its correct pressure range. Sourced directly through authorized Genie supply channels, this part carries the quality assurance that comes with genuine OEM designation. Cross-reference part number 45491GT against your Genie parts manual to confirm fitment for your specific machine configuration before ordering.
Key Features
- Genuine OEM Pressure Specification — Set to the exact 2000 PSI relief threshold required by the hydraulic system, so the circuit is protected without over- or under-pressure compromise.
- Direct Bolt-In Replacement — Engineered to match the original valve's port size, thread pattern, and mounting interface for a straightforward swap into the existing hydraulic manifold.
- Broad Z-Series Compatibility — Fits the Z-45/22D, Z-45/22DRT, Z-25/8, Z-20/8, and Z-20/8N articulating boom lifts, covering multiple platform configurations within the Genie Z-series range.
- Sustained Hydraulic Circuit Integrity — A correctly functioning relief valve keeps actuator speed, lift force, and system response consistent across all boom functions, preventing erratic or sluggish movement.
- Aerial-Lift Safety Compliance — On articulating boom lifts, hydraulic pressure regulation is directly tied to safe load handling and controlled boom movement; replacing a faulty valve with a genuine OEM unit helps restore designed system behavior.
A hydraulic relief valve acts as a pressure safety regulator within the machine's hydraulic circuit. When system pressure reaches its set limit — in this case 2000 PSI — the valve opens to divert excess fluid back to the reservoir, preventing damage to pumps, cylinders, hoses, and other hydraulic components. On articulating boom lifts, this regulation is critical: a valve that has drifted out of specification, is stuck open, or has failed to open can cause sluggish boom response, loss of lift capacity, or uncontrolled pressure spikes that stress the entire hydraulic system. Replacing a worn or failed valve with the correct genuine OEM part restores consistent, predictable hydraulic performance across all boom and platform functions.
