The Genie 101446GT is a genuine OEM Relief Valve, 280 PSI designed for Genie S series telescopic boom lifts and Z series articulating boom lifts. As a direct OEM replacement, this valve is built to the exact hydraulic pressure specification required to maintain safe and consistent system operation across compatible models. It fits a broad range of Genie booms including S-40, S-45, S-60, S-60 XC, S-60 HC, S-60 TRAX, S-60X, S-65, S-65 TRAX, S-80, S-80X, S-85, Z-135/70, and ZX-135/70. Cross-reference part number 101446GT against your parts manual to confirm fitment before ordering.
Key Features
- Rated at 280 PSI — factory-matched pressure rating ensures the hydraulic circuit opens and vents at exactly the correct threshold, protecting system components from overpressure damage.
- Genuine OEM Construction — manufactured to Genie's original hydraulic valve specification, so internal porting, seat geometry, and spring tension match the design intent of the system.
- Broad Boom Compatibility — fits a wide range of Genie S series telescopic and Z series articulating boom lifts, including XC, HC, TRAX, and X variants, covering both standard and specialty configurations.
- Drop-In Hydraulic Replacement — this valve installs directly into the existing hydraulic manifold port, retaining the original thread interface and sealing surface without rework.
- Protects Hydraulic System Integrity — a correctly functioning relief valve prevents pump cavitation, cylinder bypass, and downstream component wear caused by uncontrolled pressure spikes.
- Safety-Critical Function — on aerial boom lifts, precise hydraulic pressure regulation is essential to controlled platform movement and safe load handling at height; a worn or out-of-spec valve can compromise both.
A hydraulic relief valve acts as a pressure-safety gate within a machine's hydraulic circuit. When system pressure exceeds the rated threshold — in this case 280 PSI — the valve opens to divert fluid back to the reservoir, preventing dangerous overpressure from reaching cylinders, hoses, and actuators. On Genie boom lifts, this function is essential to smooth, controlled platform movement; if the valve fails to open at the correct pressure, the system can become sluggish, erratic, or unsafe, and if it fails to close, the circuit loses the force needed to lift and hold the platform at height. Replacing a worn or faulty relief valve with the correct OEM-spec unit restores the hydraulic system to its intended operating behavior.
