The Genie 50481GT is a genuine OEM Counterbalance Valve, 3500 PSI designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts. Sourced directly from Genie, this valve meets the exact hydraulic specifications your machine was built with, making it a direct replacement for worn or failed units on models including the S-80, S-80 XC, S-85, S-85 XC, S-80 HF, S-85 HF, Z-45/22, Z-45/25, Z-45/25J IC Power, Z-45/25J DC, and Z-45/25J Bi-Energy. As a genuine OEM component, this valve is manufactured to the same standards as the original, ensuring your boom lift operates exactly as intended after installation. Cross-reference part number 50481GT against your machine's parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Rated at 3500 PSI, this valve matches the original pressure specification, ensuring the hydraulic circuit performs as engineered — not approximated.
- Direct Drop-In Replacement — Engineered to the same port configuration and thread interface as the original, this valve installs into the existing hydraulic circuit without modification.
- Broad Boom Lift Fitment — Compatible with a wide range of Genie S-series telescopic and Z-series articulating boom lifts, including XC, HF, DC, IC Power, and Bi-Energy variants.
- Controlled Load Holding Under Pressure — A correctly functioning counterbalance valve prevents uncontrolled boom movement when hydraulic pressure fluctuates or a line fails, keeping boom positioning smooth and stable.
- Critical Safety Function — This valve is a key hydraulic safety component on aerial boom lifts. A failed or bypassing counterbalance valve can allow unintended boom drift, making prompt replacement with a correctly rated OEM part essential for safe operation at height.
A counterbalance valve is a load-holding hydraulic component that prevents a boom or cylinder from drifting or dropping under its own load weight when the hydraulic pump is not actively driving it. On telescopic and articulating boom lifts, it works by requiring a controlled pilot pressure signal before allowing fluid to flow out of the actuator — effectively locking the boom in position until a deliberate operator input is made. When this valve wears, sticks, or fails, the result can be slow boom drift, jerky movement, or in serious cases, a loss of load-holding ability, all of which compromise both machine performance and operator safety at elevation.
