The Genie 27837GT is a genuine OEM Relief Valve, 1000 PSI designed for the Genie S-60 telescopic boom lift and Z-30/20HD articulating boom lift. Sourced directly from Genie, this valve is built to the same specification as the original component installed at the factory, ensuring full hydraulic system compatibility on both machines. Cross-reference part number 27837GT against your machine's parts manual to confirm fitment before ordering. Keeping hydraulic pressure regulation accurate is critical on aerial work platforms, and this genuine replacement delivers exactly that assurance.
Key Features
- Genuine OEM Hydraulic Calibration — Factory-rated at 1000 PSI, this valve maintains the precise pressure threshold the hydraulic circuit on these boom lifts is engineered to operate within — no guesswork on pressure settings.
- Drop-In Compatibility — Engineered to match the original valve's port size, thread specification, and cracking pressure, allowing direct installation without reworking hydraulic fittings or lines.
- Fits S-60 and Z-30/20HD Boom Lifts — Confirmed for both the S-60 telescopic boom and the Z-30/20HD articulating boom, covering two distinct Genie boom-lift platforms with a single OEM part.
- Sustained Hydraulic Circuit Protection — A correctly functioning relief valve prevents dangerous pressure spikes that can damage cylinders, hoses, and pumps throughout the hydraulic system, extending the service life of connected components.
- Aerial Lift Safety Compliance — On boom lifts, uncontrolled hydraulic pressure can affect boom movement and platform stability. Replacing a worn or bypassing relief valve with a genuine OEM unit restores the pressure control the machine's safe operation depends on.
A hydraulic relief valve is a pressure-limiting safety device within the machine's hydraulic circuit. It opens at a preset pressure — in this case 1000 PSI — to divert excess fluid back to the reservoir, preventing over-pressurization that could rupture hoses, damage cylinders, or cause uncontrolled boom movement. When a relief valve wears out, sticks open, or fails to hold its rated pressure, the hydraulic system loses the ability to regulate force correctly, resulting in sluggish lift performance, erratic boom behavior, or potential damage to downstream components. Replacing this valve with the correct genuine OEM part restores proper pressure regulation and keeps the hydraulic system performing as Genie intended.
