The Genie 74508GT is a genuine OEM Check Valve, COBA-X*N 200PSI PO built for Genie TZ trailer-mounted articulating booms and Z-series articulating boom lifts, including the TZ-50/30, TZ-50, Z-34/22 N, Z-34/22 Bi-Energy, Z-30/20 N, Z-34/22 IC, and Z-34 IC. As a genuine Genie OEM part, this check valve is produced to the same standards as the original component installed at the factory, ensuring an exact fit without modification. Cross-reference part number 74508GT against your machine's parts manual to confirm it is the correct valve for your specific unit before ordering.
Key Features
- Genuine OEM Valve Spec — Manufactured to Genie's original design spec, including the correct 200PSI pilot-operated cracking pressure, so the valve performs as the circuit demands.
- Direct Drop-In Replacement — Matches the original port configuration and body dimensions for a clean installation with no rework or adaptation.
- Broad Genie Boom Fitment — Compatible with multiple Genie articulating boom families: TZ-50/30, TZ-50, Z-34/22 N, Z-34/22 Bi-Energy, Z-30/20 N, Z-34/22 IC, and Z-34 IC.
- Flow Control Integrity — A correctly functioning check valve prevents unintended reverse flow, keeping fluid moving in the intended direction and protecting downstream components from pressure spikes or backflow damage.
- Operational Safety — On articulating boom lifts, valve integrity is directly tied to controlled, predictable boom movement. Replacing a failed or bypassing check valve restores the designed response of the circuit it serves.
A check valve is a one-way flow-control component that allows fluid to pass freely in one direction while blocking reverse flow. On articulating boom lifts, check valves protect critical circuits from backpressure and uncontrolled movement — a valve that is leaking internally or stuck open can cause sluggish response, drift, or loss of hold pressure in the functions it serves. Replacing a worn or failed valve with the correct OEM unit, such as the 74508GT, restores proper directional control and protects connected components from the damage that unregulated backflow can cause.
