The Genie 29221GT is a genuine OEM Counterbalance Valve designed for the Genie Z-30/20 articulating boom lift. Sourced directly from Genie, this valve is built to the same specification as the original component installed at the factory, ensuring a direct, hassle-free replacement. Whether you are completing a scheduled hydraulic service or addressing a known valve failure, cross-reference part number 29221GT against your parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Genie's original pressure and flow specifications, so the valve responds and holds load exactly as designed for the Z-30/20's hydraulic circuit.
- Direct Drop-In Replacement — Matches the original port configuration and thread specification of the Z-30/20, allowing straightforward installation without reworking hydraulic lines or fittings.
- Confirmed Fitment for the Z-30/20 — Verified for the Genie Z-30/20 articulating boom lift; verify part number 29221GT against your serial number and parts manual before ordering.
- Consistent Load-Holding Performance — A properly functioning counterbalance valve keeps the boom cylinder from drifting under load, maintaining stable platform positioning during operation.
- Critical Safety Function — On aerial boom lifts, counterbalance valves are a primary safeguard against uncontrolled boom descent. Replacing a worn or bypassing valve with a genuine OEM part restores this protection to its intended standard.
A counterbalance valve is a hydraulic control component that prevents a cylinder from moving faster than the pump can supply fluid — essentially acting as a load-holding check against gravity or external forces acting on the boom. On an articulating boom lift like the Z-30/20, it ensures the boom arm holds its position when the hydraulic pump is not actively commanding movement, stopping the platform from drifting or dropping under the weight of the load. When a counterbalance valve wears, sticks, or begins to bypass, operators may notice slow boom drift, jerky movement, or an inability to hold the platform steady — all of which demand immediate attention on a man-lift application.
