The Genie 36648GT is a genuine OEM Counterbalance Valve, 2500 PSI designed for Genie Z-series articulating boom lifts and TMZ trailer-mounted articulating booms. As a factory-original component, this valve is manufactured to the exact pressure rating and porting configuration required by the hydraulic system, ensuring correct load-holding performance across the full range of compatible machines. This part fits a wide range of models including the Z-34/22 Bi-Energy, Z-34/22 DC, Z-34/22 N, Z-60/34, Z-80/60, Z-30/20 N, Z-30/20N RJ, Z-34/22 IC, Z-34 IC, TMZ-50/30, and TMZ-17/10. Cross-reference part number 36648GT against your parts manual to confirm fitment for your specific serial range before ordering.
Key Features
- Rated to Spec — Calibrated at 2500 PSI to match the hydraulic load-holding demands of Genie Z and TMZ articulating boom circuits — no pressure-setting guesswork required.
- Genuine OEM Quality — Factory-original construction ensures correct valve cracking pressure, port sizing, and seal material for the hydraulic circuit this part controls.
- Direct-Swap Installation — Built to the same envelope and port configuration as the original, allowing this valve to thread directly into the existing hydraulic manifold or cylinder port without adaptation.
- Broad Articulating Boom Coverage — Fits Genie Z-series articulating booms and TMZ trailer-mounted articulating booms, covering both standard and specialty configurations including Bi-Energy, DC, N, IC, and RJ variants.
- Protects Boom Function Under Load — A correctly functioning counterbalance valve prevents uncontrolled boom drift or descent when hydraulic pressure is momentarily interrupted, keeping the platform position stable during operation.
- Critical Safety Component — On aerial boom lifts, load-holding valves are a fundamental part of platform stability and safe operation at height; using the correct OEM-rated valve is essential for maintaining the machine's intended safety performance.
A counterbalance valve is a hydraulic safety and control component installed in the cylinder circuits of boom lifts to hold a load in place and prevent unintended movement. It works by blocking return oil flow from a hydraulic cylinder unless a controlled pilot signal is present, which means the boom stays in position even if a hose fails or pressure drops elsewhere in the system. When a counterbalance valve wears, leaks internally, or loses its calibrated cracking pressure, the boom may drift downward under load, respond sluggishly, or fail to hold position — all of which compromise both operational precision and platform safety at height.
