The Genie 27807GT is a genuine OEM Check Valve designed for Genie S series telescopic boom lifts and Z series articulating boom lifts. Sourced directly from Genie, this part meets the same specifications as the original component installed at the factory, making it a direct fit for the hydraulic system on compatible machines. Compatible models include a wide range of S series booms such as the S-40, S-45, S-60, S-60 XC, S-65, S-80, S-85, S-100, S-105, S-120, and S-125, as well as Z series booms including the Z-30/20 N, Z-34/22 IC, Z-45/25, Z-45/25J IC Power, Z-51/30J, Z-60/34, Z-62/40, and Z-80/60, among others. Cross-reference part number 27807GT against your Genie parts manual to confirm fitment for your specific machine before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Genie's original design tolerances, this check valve maintains correct one-directional flow control within the hydraulic circuit, ensuring the system performs as engineered.
- Direct-Fit Replacement — This check valve installs into the existing hydraulic circuit port with no adaptation needed, matching the original valve's thread pattern and body geometry.
- Broad Boom Lift Coverage — Fits a wide range of Genie S series telescopic booms and Z series articulating booms, including XC, TRAX, HF, HC, and J variants, as well as the IWP Super Series.
- Protects Hydraulic Circuit Function — A functioning check valve prevents backflow and pressure loss in the hydraulic system. A failed or worn valve can cause unintended boom drift, sluggish movement, or loss of load-holding capability.
- Critical to Safe Boom Operation — On aerial boom lifts, hydraulic check valves play a direct role in maintaining platform position and controlled movement. Replacing a faulty valve restores proper load-holding and motion control performance.
A check valve is a one-way hydraulic valve that allows fluid to flow in a single direction while blocking reverse flow. In a boom lift's hydraulic system, check valves are used to hold pressure in cylinders — keeping the boom, jib, or platform in position under load without relying solely on the pump. When a check valve wears out or fails internally, it can no longer seat properly, which allows fluid to bypass and pressure to bleed off — resulting in boom drift, slow or unresponsive movements, and potential safety concerns. Replacing a worn check valve with a correct-fitting genuine OEM part restores the hydraulic circuit to its intended operating condition.
