Genie 52376GT Relief Valve, 3500PSI

The Genie 52376GT is a genuine OEM Relief Valve, 3500PSI designed for a wide range of Genie GS scissor lifts and boom lifts, including the GS-1930, GS-2632, GS-3390, GS-5390, TZ-50/30, Z-45/25, and Z-45/25J IC Power. Sourced directly from Genie, this valve matches the original hydraulic system specifications of the machines it serves, ensuring the hydraulic circuit is protected at the correct pressure threshold. Compatible models span the full GS scissor lift lineup — from compact slab models through heavy-duty rough-terrain and dual-drive variants — as well as select trailer-mounted and articulating boom lifts. When hydraulic system integrity matters, verifying part number 52376GT against your machine's parts manual before ordering is the surest way to confirm fitment.

Key Features

• Factory-Rated Pressure Specification — Set to 3500PSI from the factory, this relief valve maintains the precise hydraulic pressure threshold the system was engineered to operate within.
• Genuine OEM Component — Built to Genie's original engineering standards, this valve delivers the same sealing performance, port geometry, and cracking accuracy as the part it replaces.
• Direct-Fit Replacement — Engineered as an exact replacement for the original valve, this part installs into the hydraulic manifold without modification or adaptation to fittings.
• Broad Scissor and Boom Lift Compatibility — Fits Genie GS scissor lifts across multiple platform sizes and drive configurations, plus TZ and Z series articulating and trailer-mounted boom lifts.
• Hydraulic System Protection — A correctly functioning relief valve prevents pressure spikes that can damage pumps, cylinders, and seals — keeping the hydraulic system within its safe operating envelope.
• Aerial Lift Safety Compliance — On aerial work platforms, proper hydraulic pressure regulation is essential to controlled lift and lower functions; a failed or out-of-spec valve can cause uncontrolled platform movement, making this a safety-critical component.

A hydraulic relief valve acts as a pressure safety device within the machine's hydraulic circuit. It is set to open at a specific pressure — in this case 3500PSI — allowing excess hydraulic fluid to return to the reservoir whenever system pressure exceeds that threshold, preventing damage to pumps, hoses, actuators, and other downstream components. On scissor lifts and boom lifts, the relief valve also plays a direct role in controlling the speed and force of platform movement during lift and lower cycles. When the valve wears, sticks open, or loses its calibrated setting, the machine may experience sluggish lift performance, erratic platform movement, excessive heat buildup in the hydraulic fluid, or an inability to hold rated load — all signs that the valve needs immediate inspection and replacement.
