The Genie 40983GT is a genuine OEM Counterbalance Valve, 1500 PSI designed for Genie telescopic and articulating boom lifts across multiple series. Sourced directly through the OEM supply chain, this valve meets the original engineering specifications for the hydraulic systems found on S-series telescopic booms and Z-series articulating booms. Compatible models include the S-40, S-45, S-60, S-65, Z-30/20 N, Z-34/22 IC, Z-34/22 Bi-Energy, Z-45/22 MP, Z-45/22, and Z-60/34 — cross-reference part number 40983GT against your machine's parts manual before ordering to confirm the correct application. As a genuine OEM part, this counterbalance valve installs directly in place of the original component with no guesswork on fit or rating.
Key Features
- Genuine OEM Hydraulic Specification — Rated at exactly 1500 PSI to match the original hydraulic circuit design, ensuring the valve opens and closes at the correct pressure threshold without over- or under-compensation.
- Direct Drop-In Replacement — Engineered to the same port configuration and body dimensions as the original, this valve installs into the existing hydraulic manifold without adapters or line modifications.
- Broad Boom Lift Coverage — Fits Genie S-series telescopic booms (S-40, S-45, S-60, S-65) and Z-series articulating booms (Z-30/20 N, Z-34/22 IC, Z-34/22 Bi-Energy, Z-45/22 MP, Z-45/22, Z-60/34).
- Smooth, Controlled Boom Movement — A correctly functioning counterbalance valve keeps boom sections and attachments from drifting or dropping under load, maintaining precise operator control throughout the full range of motion.
- Critical Safety Component — On aerial boom lifts, a failed or out-of-spec counterbalance valve can allow uncontrolled boom descent, making proper valve function essential to safe elevated-work operations.
A counterbalance valve is a hydraulic holding valve installed in the cylinder circuit of a boom lift to prevent uncontrolled movement when the boom is elevated and under load. It works by holding pressure on the load-bearing side of the cylinder, only allowing fluid to return when active pressure is applied from the pump — this is what keeps the boom from drifting or dropping when the operator releases the controls. When this valve fails or begins to bypass internally, the boom may drift downward on its own, respond sluggishly, or fail to hold position, all of which compromise both productivity and operator safety at height.
