The Genie 139323GT is a genuine OEM Counterbalance Valve, CBCA-LIN built for Genie SX telescopic boom lifts, S series booms, and Z and ZX articulating booms. As a direct OEM replacement, this valve is manufactured to the same specifications as the original, ensuring correct operation within the circuit it serves. This part is confirmed to fit models including the SX-150, SX-180, SX-135 XC, S-85 XC, Z-135/70, Z-62/40, Z-80/60, and ZX-135/70 — cross-reference part number 139323GT against your machine's parts manual to verify fitment for your specific unit before ordering.
Key Features
- Genuine OEM Construction — Built to Genie's original specifications for the CBCA-LIN counterbalance valve, ensuring correct pressure settings, port sizing, and material grade for the circuit it serves.
- Direct OEM Replacement — Designed to install in place of the original valve with no modification, restoring the valve assembly to its factory configuration.
- Broad Boom Lift Compatibility — Fits Genie SX super-boom telescopic lifts, S series telescopic booms, and Z and ZX series articulating booms, covering some of the tallest machines in the Genie lineup.
- Load-Holding Integrity — A correctly functioning counterbalance valve prevents uncontrolled movement of the boom when loads are suspended or when a line loses pressure, maintaining controlled, predictable motion.
A counterbalance valve is a load-holding control valve fitted into a fluid circuit to prevent a boom or actuator from moving unless actively commanded by the operator. It works by blocking free flow in one direction and allowing controlled flow only when pilot pressure from the opposing side of the circuit is present, which means the boom cannot drift, lower, or extend on its own if pressure is lost in a line. On large telescopic and articulating boom lifts like those in the Genie SX and Z series, where platform heights can be extreme, a worn or failed counterbalance valve can allow uncontrolled boom movement — making prompt replacement with the correct OEM part essential to safe machine operation.
