The Genie 106848GT is a genuine OEM CB Valve designed for the Z-135/70 and ZX-135/70 articulating boom lifts. Sourced directly from Genie, this counterbalance valve is an exact-fit replacement that meets the original hydraulic specifications for these machines. It is engineered to operate at the rated system pressure, ensuring consistent, controlled load-holding performance in demanding job conditions. If you're maintaining or restoring hydraulic function on a Z-135/70 or ZX-135/70, this is the correct part to spec.
Key Features
- Genuine OEM Hydraulic Specification — Built to the original pressure rating and valve geometry, this counterbalance valve delivers the precise load-holding and flow-control behavior Genie engineered into the Z-135/70 and ZX-135/70 hydraulic circuit.
- Direct Counterbalance Circuit Integration — This valve installs into the existing hydraulic circuit without adaptation, replacing the original CBGA-LHN configuration and restoring correct system function.
- Confirmed Fitment for Z-Series Articulating Booms — Verified for the Z-135/70 and ZX-135/70, two of Genie's largest articulating boom lifts, where precise hydraulic control is critical across all boom functions.
- Stable Load Control at Rated Pressure — A properly functioning counterbalance valve prevents uncontrolled boom movement under load. Worn or failed valves can cause drift, jerky motion, or loss of controlled descent — this replacement restores smooth, predictable operation.
- Aerial Lift Safety Function — On high-reach articulating booms, the counterbalance valve is a load-bearing safety component. Using a genuine OEM replacement maintains the integrity of the boom's hydraulic load-holding system and supports safe operation at height.
A counterbalance valve — also known as a CB valve — is a hydraulic load-holding device installed in the cylinder circuit of boom lifts and other hydraulic machinery. Its primary job is to prevent the boom or load from drifting or dropping when the control input is neutral, effectively locking the hydraulic cylinder in position until intentional movement is commanded. On large articulating booms like the Z-135/70 and ZX-135/70, this function is essential: without a correctly calibrated counterbalance valve, the boom can exhibit uncontrolled movement under gravity or external load. When this valve wears, leaks internally, or fails to hold its set pressure, operators may notice boom drift, sluggish response, or erratic motion — all indicators that replacement is needed promptly.
