The Genie 104799GT is a genuine OEM Solenoid Valve, 3-Position 4-Way designed for the TZ-34/20 trailer-mounted articulating boom lift, controlling the boom extend and retract circuit. As a direct Genie OEM component, this valve meets the exact hydraulic and electrical specifications of the original, ensuring the boom actuation system performs as intended. Please note that items 3A and 3B referenced in the parts manual are not included with this valve and must be purchased separately. Cross-reference part number 104799GT against your Genie parts manual to confirm this is the correct valve for your machine's configuration before ordering.
Key Features
- Genuine OEM Hydraulic Specification — Built to Genie's exact spool configuration and flow-path geometry, ensuring correct pressure differential and directional control for the boom extend/retract circuit.
- Direct-Fit Replacement — Engineered to install into the existing valve manifold on the TZ-34/20 using the original port connections, with no adaptation to the hydraulic circuit required.
- Confirmed TZ-34/20 Fitment — Specifically validated for the TZ-34/20 trailer-mounted articulating boom lift AC variant; verify your machine's configuration against part number 104799GT in your parts manual.
- Dependable Boom Actuation — A properly functioning 3-position 4-way solenoid valve delivers smooth, responsive extension and retraction; a degraded or failed valve can cause sluggish movement, unintended drift, or complete loss of boom function.
- Aerial-Lift Safety Integrity — Directional control valves are a critical element of boom positioning on aerial lifts; using a correctly specified OEM replacement supports the hydraulic integrity required for safe elevated operation.
- Important Parts Note — Items 3A and 3B shown in the Genie parts diagram are not included and must be ordered separately; confirm your full parts list before submitting your order.
A 3-position 4-way solenoid valve directs hydraulic fluid through one of four ports depending on which of its three positions is energized — allowing the boom to extend, retract, or hold position when the solenoid is at center. On the TZ-34/20, this valve is the primary directional control component for the boom extend and retract function, translating electrical signals from the operator controls into precise hydraulic movement. When the valve wears, sticks, or fails electrically, the boom may respond erratically, fail to hold its position, or stop moving altogether — making prompt replacement essential to keeping the machine operational and safe.
