The Genie 84333GT is a genuine OEM Counter Balance Valve, 3300 PSI, designed for the TZ-34/20 trailer-mounted articulating boom lift. Sourced directly from Genie, this valve is built to the exact pressure rating and porting configuration required for the TZ-34/20 hydraulic system, ensuring proper load-holding performance without improvisation or adaptation. Cross-reference part number 84333GT against your Genie parts manual to confirm this is the correct valve for your serial range and configuration before ordering.
Key Features
- Exact OEM Pressure Rating — Factory-set at 3300 PSI to match the TZ-34/20 hydraulic circuit specification, preserving correct load-holding thresholds with no pressure-relief guesswork.
- Direct Hydraulic Port Match — Engineered to the same port configuration as the original valve, allowing straightforward installation into the existing hydraulic plumbing on the TZ-34/20.
- Dedicated TZ-34/20 Fitment — Designed specifically for the Genie TZ-34/20 trailer-mounted articulating boom, ensuring this valve integrates correctly with the machine's boom and axle hydraulic circuits.
- Controlled Boom Movement Under Load — A properly functioning counter balance valve holds the boom in position and controls descent speed under load, preventing uncontrolled drift that can compromise personnel safety.
- Critical Safety Function — Counter balance valves are a primary load-holding safety component on aerial booms. A failed or incorrectly rated valve can result in uncontrolled boom movement, making genuine OEM specification essential for this part.
A counter balance valve is a hydraulic control component that holds a load in position by preventing fluid from exhausting out of a cylinder until sufficient pilot pressure is applied from the opposite side. On the TZ-34/20, this valve maintains boom position during lifting and lowering operations, ensuring movement is smooth, deliberate, and proportional to operator input. When a counter balance valve fails — whether through internal leakage, seal degradation, or an incorrect pressure setting — the boom can drift, drop unexpectedly, or move erratically under load, creating a serious hazard for the operator and anyone nearby.
