The Genie 139516GT is a genuine OEM Relief Valve, 250PSI designed for the Genie Z-51/30J articulating boom lift, fitting manifold 139391GT from SN Z452510A-39751 and from SN Z452511B-1607. As a direct OEM replacement, this valve is manufactured to the same specification as the original, ensuring a proper fit within the manifold assembly it serves. Confirm part number 139516GT and your machine's serial number against your parts manual before ordering to be certain this is the correct item for your unit.
Key Features
- Genuine OEM Construction — Built to Genie's original specification, with the correct pressure rating and dimensional tolerances for a reliable seat and seal within manifold 139391GT.
- Exact Pressure Rating — Rated at 250PSI to match the circuit requirements of the manifold assembly, maintaining proper system pressure without deviation.
- Direct Manifold Fit — Engineered specifically for manifold 139391GT on the Z-51/30J, so this valve installs into the existing manifold bore without modification.
- Serial-Range Specific — Validated for Z-51/30J units from SN Z452510A-39751 and from SN Z452511B-1607, keeping your machine correctly speced for its production range.
- Operational Integrity — A correctly rated relief valve protects the circuit it serves from overpressure, supporting safe, controlled operation of the boom functions it governs.
A relief valve regulates pressure within a hydraulic manifold by opening at a set threshold — in this case 250PSI — to divert fluid and prevent pressure from building beyond safe limits. When the valve fails or drifts from its rated setting, the circuit it protects may experience erratic performance, sluggish boom movement, or uncontrolled pressure spikes. Replacing a faulty valve with the correct OEM part, part number 139516GT, restores the pressure control the manifold 139391GT was designed to deliver and keeps the Z-51/30J operating within its intended parameters.
