The Genie 65749GT is a genuine OEM Relief Valve, 3000PSI, #8 designed for Genie GS-3390, GS-4390, and GS-5390 large-frame scissor lifts. Sourced directly from Genie, this part meets the same specifications as the component installed at the factory, ensuring a correct, confidence-worthy fit within your machine's hydraulic system. This relief valve is engineered for the demanding pressure requirements of the GS-3390, GS-4390, and GS-5390 platforms, making it the dependable choice when your original component needs replacing. Cross-reference part number 65749GT against your Genie parts manual to confirm fitment before ordering.
Key Features
- OEM-Rated Pressure Accuracy — Factory-set at 3000PSI, this genuine OEM valve operates at the exact pressure threshold required to protect the hydraulic circuit on Genie large-frame scissor lifts.
- Direct-Connect #8 Port Fitting — The #8 port sizing matches the hydraulic plumbing on compatible GS series machines, allowing straightforward installation without reworking connections.
- Fits Genie GS Large-Frame Scissor Lifts — Confirmed fitment for the GS-3390, GS-4390, and GS-5390, covering the upper end of Genie's GS scissor lift lineup.
- Hydraulic System Protection — A correctly functioning relief valve prevents pressure spikes from damaging pumps, cylinders, and hoses. A failed or out-of-spec valve can allow over-pressurization that causes costly downstream damage.
- Platform Stability and Safe Operation — On aerial scissor lifts, consistent hydraulic pressure control is directly tied to smooth, predictable platform lift and hold — making this component critical to safe working-at-height operations.
A relief valve is a pressure-regulating safety component within the hydraulic circuit. Its job is to open at a set pressure threshold — in this case 3000PSI — and divert excess hydraulic fluid back to the reservoir, preventing dangerous over-pressurization in the system. On large-frame scissor lifts like the GS-3390, GS-4390, and GS-5390, the relief valve protects pumps, actuators, and hose assemblies from pressure surges that can occur during lifting or when a load is held at height. When this valve wears, sticks open, or loses its calibrated set point, the machine may experience sluggish lift performance, unintended platform drift, or — in a worst-case scenario — uncontrolled hydraulic pressure that puts components and operators at risk.
