The Genie 21679GT is a genuine OEM 3-Way Solenoid Cartridge Valve designed for Z-45/22D and Z-45/22DRT articulating boom lifts. Sourced directly from Genie, this valve is built to the same specification as the original component installed at the factory, ensuring correct electrical and hydraulic compatibility on every installation. Whether you are restoring full boom function after a valve failure or completing a scheduled hydraulic service, this cartridge valve delivers the exact fit and performance your machine demands. Cross-reference part number 21679GT against your Genie parts manual to confirm this is the correct valve for your application.
Key Features
- Genuine OEM Hydraulic Specification — Built to Genie's original 12V solenoid actuation and flow-path specification, ensuring the valve opens, shifts, and seals exactly as the hydraulic circuit requires.
- Cartridge-Style Direct Replacement — Threaded cartridge format installs directly into the existing valve body cavity with no machining or adaptation, restoring the hydraulic circuit in a straightforward service procedure.
- Confirmed Fitment for Z-45/22 Series Booms — Engineered specifically for the Z-45/22D and Z-45/22DRT articulating boom lifts, so you can order with confidence knowing this component matches your machine's hydraulic manifold.
- Restores Full Boom Movement and Control — A correctly functioning 3-way solenoid valve routes hydraulic flow to the right actuator at the right time. A failed or stuck valve results in sluggish, erratic, or completely unresponsive boom function.
- Operational Safety on Elevated Equipment — Precise hydraulic directional control is critical on articulating boom lifts. Replacing a faulty valve with a genuine OEM component restores the predictable, stable boom response that safe operation at height depends on.
A 3-way solenoid cartridge valve controls the direction of hydraulic fluid flow within a boom lift's hydraulic circuit. When an operator activates a boom function, the 12V solenoid energizes, shifting the valve's internal spool or poppet to direct pressurized fluid to the appropriate actuator — such as a cylinder controlling lift, swing, or articulation. When the solenoid de-energizes, the valve returns to its default flow path, stopping or redirecting movement. If this valve fails — through coil burnout, internal leakage, or contamination — the affected boom function may become slow, uncontrollable, or entirely inoperative, making prompt replacement essential for restoring safe and productive machine performance.
