The Genie 45481GT is a genuine OEM Check Valve designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts, including the S-100, S-105, S-120, S-125, Z-30/20HD, Z-45/22D, and Z-45/22DRT. As a factory-authorized component, this check valve meets the exact specifications Genie requires for correct hydraulic system operation. Cross-reference part number 45481GT against your machine's parts manual to confirm fitment before ordering. When it comes to hydraulic integrity on aerial equipment, sourcing genuine OEM is the right call.
Key Features
- Genuine OEM Hydraulic Precision — Built to Genie's exact flow and pressure specifications, ensuring the check valve opens and seats correctly under operating hydraulic loads.
- Direct-Fit Replacement — Engineered to install in the same port and orientation as the original, with matching thread spec and body dimensions for a straightforward swap.
- Broad Boom Lift Compatibility — Fits Genie S-series telescopic booms (S-100, S-105, S-120, S-125) and Z-series articulating booms (Z-30/20HD, Z-45/22D, Z-45/22DRT).
- Protects Hydraulic Circuit Integrity — A correctly functioning check valve prevents backflow and pressure loss, keeping boom movements smooth, controlled, and predictable under load.
- Critical Safety Component — On aerial boom lifts, hydraulic check valves help hold boom position and prevent unintended movement — making correct spec and condition essential for safe elevated operation.
A check valve is a one-way flow control component within the hydraulic system. Its job is to allow fluid to travel in one direction while blocking reverse flow, which helps maintain pressure and holds the boom in position when the system is at rest. On aerial boom lifts, a worn or failed check valve can cause the boom to drift or drop unexpectedly, which compromises both machine performance and operator safety. Replacing a faulty check valve with the correct OEM part restores proper hydraulic control and ensures the machine behaves as designed.
