The Genie 111392GT is a genuine OEM Check Valve, 150 PSI designed for Genie S-80 and S-85 telescopic boom lifts. As a factory-sourced component, this check valve is built to the same specification as the part it replaces, ensuring correct pressure rating and hydraulic compatibility right out of the box. Cross-reference part number 111392GT against your machine's parts manual to confirm fitment before ordering. If you're experiencing hydraulic drift, pressure loss, or erratic boom movement on your S-80 or S-85, this check valve is a critical component to inspect and replace.
Key Features
- Correct Pressure Rating — Factory-spec 150 PSI rating ensures the valve opens and closes at the precise threshold your hydraulic circuit requires.
- Genuine OEM Sourcing — Manufactured to Genie's original design tolerances, delivering a direct, drop-in replacement with no guesswork on seal compatibility or port sizing.
- Confirmed Fitment — Fits Genie S-80 and S-85 telescopic boom lifts; verify using part number 111392GT in your Genie parts manual.
- Hydraulic Circuit Integrity — A correctly functioning check valve prevents backflow and holds boom position under load, keeping the hydraulic system operating as designed.
- Safety-Critical Function — On aerial boom lifts, check valve failure can result in unintended boom drift or loss of platform position — replacing a worn valve promptly is essential for safe elevated operation.
A check valve is a one-way flow control device within the hydraulic system that allows fluid to move in a single direction while blocking reverse flow. On telescopic boom lifts like the S-80 and S-85, check valves are used to hold cylinder positions, maintain boom elevation under load, and protect sensitive circuits from pressure spikes. When a check valve wears out or fails internally, the result is typically hydraulic drift — where the boom or platform slowly descends or shifts without operator input — which is both a performance issue and a serious safety concern. Replacing a faulty check valve with the correct 150 PSI-rated OEM unit restores the hydraulic circuit to its intended behavior and ensures the machine performs reliably at height.
