The Genie 77410GT is a genuine OEM Counterbalance Valve, 1500 PSI built for Genie articulating and telescopic boom lifts, including Z-series models such as the Z-45/25, Z-45/25J Bi-Energy, Z-45/25J IC Power, Z-51/30J, and Z-62/40, as well as the S-45 XC telescopic boom. Sourced directly from Genie, this valve meets the original design specification for the circuit it serves. Cross-reference part number 77410GT against your machine's parts manual to confirm it is the correct valve for your unit before ordering.
Key Features
- Genuine OEM Quality — Manufactured to Genie's original pressure rating and dimensional specification, ensuring the valve operates at the correct 1500 PSI set point for the circuit it controls.
- Direct OEM Replacement — Designed to install in the same position as the original, with matching port configuration and thread form for a straightforward swap.
- Broad Boom Lift Fitment — Fits a wide range of Genie Z-series articulating booms and S-series telescopic booms, including the Z-45/25J Bi-Energy, Z-62/40, Z-33 DC Power, and S-45 XC, among others.
- Load-Holding Integrity — A correctly functioning counterbalance valve holds the load securely in position and controls the speed of descent under load; a worn or out-of-spec valve can allow uncontrolled drift or erratic movement.
- Operational Safety — On aerial boom lifts, a counterbalance valve is a critical load-holding component. Replacing a failed unit with the correct OEM part helps restore the safe, controlled operation the machine was designed to deliver.
A counterbalance valve is a hydraulic pressure-control valve that prevents a load from dropping uncontrollably if a line loses pressure or a component fails. It works by holding a set back-pressure on the cylinder, allowing movement only when positive pilot pressure is applied by the machine's controls. On boom lifts, this valve is essential to safe boom positioning — when it wears, leaks internally, or drifts from its set pressure, the boom may creep, lower unevenly, or respond unpredictably under load. Replacing it with a genuine Genie part rated to the correct 1500 PSI specification restores the predictable, controlled performance the machine was engineered for.
