Genie 104057GT 1/4" Hydrostatic Relief Valve

The Genie 104057GT is a genuine OEM 1/4" Hydrostatic Relief Valve designed for Genie GS large-platform scissor lifts, including the GS-3384, GS-3390, GS-4390, and GS-5390. As a direct OEM replacement, this valve is built to the same specification as the original component installed at the factory, ensuring a correct, trouble-free installation. Cross-reference part number 104057GT against your Genie parts manual to confirm fitment before ordering. When your hydraulic system needs restoration, this valve delivers the precise pressure regulation your machine depends on.

Key Features

• Genuine OEM Pressure Rating — Manufactured to Genie's original specification, this valve opens and relieves at the correct set pressure for your machine's hydrostatic circuit — not an approximation.
• Direct-Fit Replacement — Engineered as a drop-in replacement for the original valve, with matching port size and thread configuration for straightforward installation.
• Confirmed Scissor Lift Fitment — Fits the Genie GS-3384, GS-3390, GS-4390, and GS-5390, covering the larger rough-terrain and heavy-duty models in the GS scissor lift family.
• Protects the Hydrostatic Drive Circuit — A correctly functioning relief valve prevents over-pressurization of the hydraulic drive system, protecting pumps, motors, and hoses from damage caused by excess pressure spikes.
• Safety-Critical Hydraulic Component — On aerial scissor lifts, proper hydraulic pressure control is directly tied to safe platform movement and machine braking. A failed or bypassing relief valve can result in uncontrolled drive behavior or loss of holding force.

A hydrostatic relief valve is a pressure-control component within the machine's hydraulic drive circuit. It acts as a safety mechanism, opening to divert hydraulic fluid when system pressure climbs beyond the design limit, protecting downstream components like motors and pumps from damage. When this valve fails — whether by sticking open, sticking closed, or leaking internally — the machine may exhibit sluggish drive response, excessive heat buildup in the hydraulic system, or an inability to hold position on a grade. Replacing a worn or faulty valve with a genuine OEM part restores the hydraulic system to its intended operating parameters and keeps the machine performing safely and predictably.
