The Genie 218144GT is a genuine OEM ZX135 Function Enable Valve designed for Genie telescopic and articulating boom lifts, including the SX-150, SX-180, SX-135 XC, S-80 XC, S-85 XC, S-80 HF, S-85 HF, SX-105 XC, SX-125 XC, and ZX-135/70. Sourced directly from Genie, this valve meets the original engineering specifications for the hydraulic control systems found on these large-platform boom lifts. Cross-reference part number 218144GT against your parts manual to confirm fitment for your specific unit before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the exact flow-rate and pressure tolerances specified for Genie boom-lift hydraulic circuits, ensuring the valve opens and closes precisely as the control system commands.
- Direct Drop-In Replacement — Engineered to match the original port configuration and mounting interface, this valve seats and seals into the existing hydraulic manifold without adaptation.
- Broad Large-Boom Compatibility — Fits Genie SX super-boom telescopic lifts, S-series telescopic booms, and the ZX-135/70 articulating boom, covering some of the tallest machines in the Genie fleet.
- Restores Full Hydraulic Function Authorization — A functioning enable valve is the system's gatekeeper: it permits hydraulic flow to reach boom and platform functions only under the correct operating conditions, keeping machine movements controlled and intentional.
- Safety-Critical Control Component — On aerial boom lifts, the function enable valve is a key element of the machine's hydraulic interlock system. A failed or leaking valve can prevent platform functions from operating or, in some failure modes, allow unintended movement — making prompt replacement with a genuine OEM part essential.
The function enable valve acts as a hydraulic gatekeeper in a boom lift's control circuit. When the operator activates platform or boom controls, the valve receives a command signal — typically electrical or pilot pressure — and opens to allow pressurized hydraulic fluid to reach the relevant actuators, enabling movement of the boom, platform, or both. When the signal is removed or a safety interlock is triggered, the valve closes and blocks flow, stopping all function movement. A worn or failed enable valve can manifest as sluggish or unresponsive boom functions, unintended movement, or a complete loss of platform control — any of which creates a serious operational hazard on a large aerial boom lift and demands immediate attention.
