The Genie 62259GT is a genuine OEM Check Valve, 30 PSI designed for Genie telescopic and articulating boom lifts, including the S-80, S-85, and Z-60/34. Sourced directly from Genie, this part meets the exact specifications of the original component installed at the factory. Cross-reference part number 62259GT against your Genie parts manual to confirm fitment for your specific machine configuration. A correctly functioning check valve is critical to maintaining hydraulic system integrity on aerial lifts, making OEM accuracy essential.
Key Features
- OEM-Rated Cracking Pressure — Calibrated to the 30 PSI threshold specified for the hydraulic circuit, ensuring the valve opens and seals at the precise pressure the system requires.
- Direct Hydraulic Line Replacement — Engineered to match the original port sizing and connection interface, allowing this check valve to swap into position without modification to lines or fittings.
- Broad Boom Lift Coverage — Fits Genie S-series telescopic booms and Z-series articulating booms, including the S-80, S-85, and Z-60/34.
- Hydraulic Flow Control — Maintains one-directional fluid flow within the hydraulic circuit, protecting actuators and cylinders from backflow pressure that can cause erratic or uncontrolled movement.
- Platform Safety Integrity — On aerial boom lifts, a failed check valve can compromise boom function and load-holding capability; replacing it with a genuine OEM part restores designed system behavior and keeps the machine operating within its rated parameters.
A check valve is a one-way hydraulic component that allows fluid to flow freely in a single direction while blocking reverse flow. In boom lift hydraulic systems, check valves protect cylinders and actuators from unintended drift or pressure loss caused by backflow, which is especially critical when a platform is elevated and under load. When this valve fails — through wear, contamination, or seat damage — the affected circuit may allow slow cylinder drift, spongy boom response, or loss of position holding, all of which compromise safe operation and machine reliability.
