The Genie 77495GT is a genuine OEM Relief Valve designed for the Z-80/60 articulating boom lift. Sourced directly from Genie, this part carries the exact pressure rating and dimensional spec required by the Z-80/60 hydraulic system, so it drops in as a true direct replacement. Cross-reference part number 77495GT against your machine's parts manual to confirm fitment before ordering. Keeping the hydraulic system operating at its correct relief pressure is critical on an articulating boom of this size, and this valve delivers precisely that.
Key Features
- Correct Pressure Rating — Factory-set at 1300 PSI to match the Z-80/60 hydraulic circuit specification exactly — no field adjustment needed after installation.
- Genuine OEM Construction — Built to Genie's original design tolerances, ensuring the valve seat, spring, and body materials meet the same hydraulic-duty grade as the part it replaces.
- Direct-Fit Replacement — Engineered to match the original port configuration and thread spec of the Z-80/60, so installation uses standard tooling and follows the existing service procedure.
- Verified Fitment for the Z-80/60 — Confirmed compatibility with the Z-80/60 articulating boom lift — use part number 77495GT when sourcing to ensure you receive the correct valve for this model.
- Hydraulic System Integrity — A properly functioning relief valve protects pumps, cylinders, and hoses from overpressure damage; a failed or incorrectly rated valve can cause erratic boom movement, component wear, or system failure.
- Aerial Lift Safety Compliance — On large articulating booms, maintaining correct hydraulic relief pressure is a genuine operational safety requirement — this part helps keep the machine performing within its designed operating parameters.
A relief valve is a pressure-control device within the hydraulic circuit that opens automatically when system pressure reaches a set threshold — in this case, 1300 PSI — allowing excess fluid to bypass back to the reservoir rather than building to damaging levels. On an articulating boom like the Z-80/60, the relief valve protects critical hydraulic components including the lift, swing, and telescope cylinders from overpressure spikes during heavy load cycles or sudden movement changes. When a relief valve fails — whether by sticking open, sticking closed, or drifting off its set pressure — the result is typically sluggish or uncontrolled boom movement, excessive heat buildup in the hydraulic fluid, or accelerated wear to downstream components.
