The Genie 104798GT is a genuine OEM Solenoid Valve, 3-Position 4-Way designed for the TZ-34/20 trailer-mounted articulating boom lift, controlling the primary boom up/down function. As a direct Genie OEM component, this valve is built to the exact specifications required for proper hydraulic circuit operation on the TZ-34/20. Please note that items 4A and 4B referenced in the parts manual are not included with this valve and must be purchased separately. Always cross-reference part number 104798GT against your machine's parts manual to confirm this is the correct valve for your application before ordering.
Key Features
- Genuine OEM Hydraulic Precision — Built to Genie's exact flow and pressure tolerances for a 3-position 4-way solenoid valve, ensuring correct hydraulic switching response in the primary boom circuit.
- Direct-Fit Replacement — Engineered specifically for the TZ-34/20 trailer-mounted articulating boom, connecting directly into the existing hydraulic and electrical interfaces without adaptation.
- Primary Boom Up/Down Control — Governs the critical up/down movement of the primary boom, making correct valve operation essential to full range-of-motion performance on the TZ-34/20.
- Confirmed TZ-34/20 Fitment — Verified for the Genie TZ-34/20 trailer-mounted articulating boom lift; cross-reference 104798GT with your parts manual to confirm applicability to your serial range.
- Partial Assembly — Know What's Included — This valve ships as a standalone unit; associated components listed as items 4A and 4B in the parts diagram are sold separately and must be ordered independently to complete the assembly.
- Boom Movement Safety Integrity — A failed or leaking solenoid valve in the primary boom circuit can cause uncontrolled or absent boom movement — a direct safety concern on any aerial work platform. Replacing a worn valve restores predictable, controlled boom operation.
A 3-position 4-way solenoid valve is a hydraulic control component that routes pressurized fluid to extend, retract, or hold a hydraulic actuator — in this case, the primary boom lift cylinder on the TZ-34/20. The three positions correspond to extend, retract, and a neutral center position that holds the boom stationary; the four-way designation refers to the four hydraulic ports the valve manages. When this valve fails — whether through internal leakage, electrical coil burnout, or spool wear — the primary boom may move sluggishly, drift from position, or stop responding entirely, compromising both productivity and safe operation of the machine.
