The Genie 122656GT is a genuine OEM Check Valve, 30 PSI designed for Genie S-series telescopic boom lifts, including the S-80, S-80X, S-85, S-80 XC, S-85 XC, S-80 HF, and S-85 HF. Sourced directly from Genie, this part meets the exact hydraulic specifications of the original component it replaces. Cross-reference part number 122656GT against your machine's parts manual to confirm fitment before ordering. Built to maintain precise pressure control within the hydraulic system, this check valve helps keep your boom operating safely and consistently across its full range of motion.
Key Features
- OEM-Rated at 30 PSI — Factory-set cracking pressure matches the hydraulic circuit requirements of the original valve, ensuring consistent one-directional flow control without adjustment.
- Direct-Swap Hydraulic Fitment — Engineered to the same port configuration and thread spec as the original, allowing straightforward installation in the existing hydraulic circuit.
- Broad S-Series Coverage — Fits the S-80X, S-80, S-85, S-80 XC, S-85 XC, S-80 HF, and S-85 HF telescopic boom lifts — one part number covering the full S-80/85 family.
- Prevents Hydraulic Backflow — A correctly functioning check valve stops pressurized fluid from flowing in the wrong direction, preventing unintended boom drift or cylinder creep under load.
- Boom Safety Integrity — On telescopic boom lifts operating at height, a failed or leaking check valve can compromise boom hold and stability. Replacing this component with a genuine OEM part supports the hydraulic system's ability to maintain safe platform positioning.
A check valve is a one-way flow control device in the hydraulic system. It allows pressurized fluid to pass freely in the intended direction while blocking reverse flow, which is critical for holding a boom or cylinder in position once extended. On telescopic boom lifts like the S-80 and S-85 series, check valves are used throughout the hydraulic circuit to maintain pressure, protect against backpressure spikes, and prevent unintended movement when the machine is stationary. When a check valve fails — through wear, contamination, or a faulty seal — fluid can bypass the valve in both directions, leading to pressure loss, slow or erratic boom response, or gradual drift that compromises safe operation at height.
