Genie 27010GT Beam Lock Off Valve

The Genie 27010GT is a genuine OEM Beam Lock Off Valve designed for a broad range of Genie telescopic boom lifts, articulating boom lifts, and rough-terrain scissor lifts. Sourced directly from Genie, this valve meets the same specifications as the original component installed at the factory, making it a direct replacement for worn or failed units. This part fits machines across the S-series telescopic booms — including the S-40, S-45, S-60, S-65, S-80, and S-85 — as well as GS rough-terrain scissor lifts such as the GS-2668 RT, GS-3268 RT, GS-2669RT, GS-3369RT, GS-4069RT, GS-3384, GS-3390, GS-4390, and GS-5390, and Z-series articulating booms including the Z-34/22 IC, Z-34 IC, Z-45/22, Z-45/22 MP, Z-45/25, Z-45/25J IC Power, Z-60/34, and Z-62/40. Cross-reference part number 27010GT against your Genie parts manual to confirm the correct application before ordering.

Key Features

• Genuine OEM Hydraulic Integrity — Built to the same valve tolerances and flow-control specifications as the original, ensuring the lock off function performs exactly as engineered.
• Direct Drop-In Replacement — The valve connects to existing hydraulic lines and mounting points without modification, simplifying the swap on any compatible machine.
• Wide Fitment Coverage — Fits Genie S-series telescopic booms, GS rough-terrain scissor lifts, and Z-series articulating booms, covering a large portion of the Genie aerial lift fleet.
• Restores Positive Hydraulic Lockout — A correctly functioning lock off valve prevents unintended hydraulic flow to the boom or lift circuit, keeping the machine responsive and under operator control at all times.
• Critical Safety Component — On aerial work platforms, a failed or leaking lock off valve can allow uncontrolled movement of the boom or platform, making prompt replacement essential for safe operation and regulatory compliance.

A lock off valve — sometimes called a hydraulic lock valve or load-holding valve — controls and isolates hydraulic flow within a specific circuit on the machine. In boom lifts and scissor lifts, this valve holds the boom, arm, or platform firmly in position by preventing fluid from bypassing back through the system when the controls are not actively engaged. When the valve wears, sticks, or develops an internal leak, operators may notice slow or unintended drift of the boom or platform, which compromises both precision and safety. Replacing a faulty valve with a correctly rated OEM unit restores the hydraulic system's ability to hold position reliably, which is fundamental to safe elevated-work operations.
