The Genie 1288378GT is a genuine OEM Relief Valve, 3500 PSI designed for the Genie S-65 XC telescopic boom lift. As a factory-sourced hydraulic component, this valve is built to the exact pressure rating and dimensional spec required by the S-65 XC, ensuring correct pressure regulation within the hydraulic circuit it serves. Cross-reference part number 1288378GT against your machine's parts manual to confirm it is the correct valve for your unit before ordering.
Key Features
- Exact Pressure Rating — Factory-set at 3500 PSI, matching the precise specification required by the S-65 XC hydraulic system.
- Genuine OEM Quality — Sourced directly from Genie, this valve meets OEM dimensional and material standards for a direct, correct-fit installation.
- Built for the S-65 XC — Confirmed fitment for the Genie S-65 XC telescopic boom lift; verify against your serial number and parts manual before ordering.
- System Pressure Control — A properly functioning relief valve protects the hydraulic circuit from overpressure, safeguarding components throughout the system. A failed or out-of-spec valve can cause erratic operation or component damage.
A relief valve is a pressure-control component within a hydraulic circuit. It opens at a set pressure — in this case 3500 PSI — to divert excess fluid and prevent overpressure that could damage pumps, cylinders, hoses, or control components. When a relief valve fails or drifts out of its rated setting, the machine may exhibit sluggish or erratic boom movement, unusually high system heat, or loss of lifting capacity. Replacing a worn or failed valve with the correct OEM part restores pressure regulation and protects the broader hydraulic system.
