The Genie 40423GT is a genuine OEM Solenoid Valve, 20V designed for Genie Z-series articulating boom lifts, including the Z-30/20 N, Z-30/20, Z-34/22 N, Z-34/22 DC, and Z-34/22 Bi-Energy. As a direct OEM replacement, this valve is built to the same specification as the original, ensuring correct voltage rating and hydraulic compatibility straight out of the box. Cross-reference part number 40423GT against your machine's parts manual to confirm fitment before ordering.
Key Features
- Correct 20V Coil Rating — Matched to the electrical system of compatible Z-series articulating booms, ensuring the coil energizes fully and the valve opens and closes at the correct threshold.
- Genuine OEM Construction — Manufactured to Genie's original design tolerances, so port sizing, thread specification, and seal materials meet the same standards as the part it replaces.
- Direct-Swap Installation — Replaces the original solenoid valve without modification, using the same mounting configuration and hydraulic connections as the factory-installed component.
- Broad Z-Series Coverage — Fits the Z-30/20 N, Z-30/20, Z-34/22 N, Z-34/22 DC, and Z-34/22 Bi-Energy, covering multiple variants within the compact Z-series articulating boom family.
- Hydraulic System Integrity — A properly functioning solenoid valve maintains precise control of hydraulic flow to boom and drive functions; a failed valve can result in sluggish response, unintended movement, or complete loss of a hydraulic circuit.
- Critical Safety Function — Solenoid valves govern directional control in aerial lift hydraulic circuits. Using a correctly rated OEM replacement is essential to maintaining the predictable, controlled operation required for safe working at height.
A solenoid valve is an electro-hydraulic component that uses an energized coil to shift an internal spool or poppet, opening or closing a hydraulic passage in response to an electrical signal from the machine's control system. On articulating boom lifts, these valves direct fluid to the cylinders that control boom articulation, extension, and drive functions. When a solenoid valve fails — whether through coil burnout, spool wear, or seal degradation — the affected hydraulic function may become unresponsive, operate erratically, or fail to hold position, directly impacting both productivity and operator safety.
