The Genie 34751GT is a genuine OEM Sun Counterbalance Valve designed for Genie S-60, S-65, S-80, and S-85 telescopic boom lifts. Sourced directly from Genie's authorized parts supply chain, this valve delivers an exact match to the original component installed at the factory. Cross-reference part number 34751GT against your machine's parts manual to confirm fitment before ordering. Replacing a worn or failed counterbalance valve with the correct OEM component restores proper hydraulic function and keeps your boom operating as intended.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to the exact pressure-relief and load-holding specifications of the original Sun valve, ensuring correct cracking pressure and flow characteristics for telescopic boom hydraulics.
- Direct Cartridge Replacement — Engineered to thread directly into the existing valve body with no re-porting or adapters required, matching the original cartridge envelope and seat geometry.
- Confirmed Fitment for S-Series Booms — Compatible with Genie S-60, S-65, S-80, and S-85 telescopic boom lifts, covering both standard and XC configurations in this platform family.
- Controlled Boom Movement Under Load — A properly functioning counterbalance valve holds the boom firmly in position and meters descent smoothly; a failed valve can cause uncontrolled drift or erratic lowering behavior.
- Critical Safety Component — Counterbalance valves are load-holding devices integral to aerial-lift safety. Using a genuine OEM replacement ensures the valve meets the rated holding capacity required for safe elevated operation.
A counterbalance valve is a hydraulic load-holding device fitted in the boom's lift circuit to prevent unintended movement when the boom is raised or when a load is suspended. It works by requiring a controlled pilot signal to open, which means the boom can only lower in a deliberate, metered fashion — not from gravity or backpressure alone. When this valve wears, sticks, or fails, operators may notice the boom drifting downward on its own, jerky or inconsistent lowering, or a complete inability to lower the boom under hydraulic command — all of which signal an immediate need for replacement.
