As a direct OEM replacement, this valve meets Genie's original specifications — no guesswork, no adaptation, and no compromise on performance. It is confirmed compatible with a wide range of models including the S-40, S-45, S-100HD, S-120HD, Z-30/20 N, Z-34/22, Z-45/22, Z-60/34, and additional S and Z series variants. Cross-reference part number 31106GT against your machine's parts manual to confirm fitment for your specific unit before ordering.
Key Features
- Genuine OEM Quality — Built to Genie's original valve specifications, ensuring correct pressure rating and flow characteristics for the circuit this valve serves.
- Direct OEM Replacement — Engineered to install in place of the original valve with correct port configuration and body dimensions for a clean, straightforward swap.
- Broad Boom Lift Compatibility — Fits a wide range of Genie S-series telescopic and Z-series articulating boom lifts, including the S-40, S-45 XC, S-100HD, S-120HD, Z-34/22, Z-45/22, Z-60/34, TZ-50, and additional models.
- Load-Holding Integrity — A correctly functioning counterbalance valve holds a suspended load securely against uncontrolled movement. A worn or failed valve can allow drift or uncontrolled lowering, directly affecting platform stability.
- Operational Safety — Counterbalance valves are a critical load-control component on aerial boom lifts. Using the correct OEM part ensures the valve operates at its rated pressure and responds predictably under load.
A counterbalance valve is a load-holding control valve that prevents a boom or cylinder from moving unintentionally under an external load — such as the weight of the platform and its occupants. It works by requiring a positive, controlled pilot signal before allowing fluid to flow in the load-lowering direction, which stops the boom from drifting or dropping if a line loses pressure. When a counterbalance valve wears, sticks, or fails to seal properly, the result can be slow drift of the boom, erratic lowering, or loss of load-holding capability — all of which require immediate attention on a manned aerial lift.
