The Genie 161538GT is a genuine OEM Check Valve, 65 PSI designed for Genie S and SX telescopic boom lifts and Z and ZX articulating boom lifts, including models SX-150, S-60 XC, S-65 XC, S-60 HF, S-65 HF, SX-180. Sourced directly from Genie, this check valve matches the original component specification, ensuring it performs exactly as the machine was engineered to operate. Fitment covers a wide range of S, SX, Z, and ZX series booms — cross-reference part number 161538GT against your parts manual to confirm compatibility with your specific unit. This is the right part when the original has failed or is due for replacement and you need confidence in the component going back in.
Key Features
- OEM-Specified Cracking Pressure — Rated at 65 PSI to match the hydraulic system's original design threshold, ensuring the valve opens and holds at the correct pressure without over- or under-compensating.
- Prevents Unintended Steer Cylinder Movement — This check valve locks the right front steer cylinder in position when steering input is not active, stopping the cylinder from drifting and keeping directional control predictable.
- Direct OEM Replacement — Engineered to the same geometry and port configuration as the original, this valve installs directly into the existing hydraulic circuit without modification.
- Broad Boom Lift Compatibility — Fits a wide range of Genie telescopic and articulating boom lifts across the S, SX, Z, and ZX series, including XC, HF, TRAX, and J variants.
- Steering System Integrity — A failed or bypassing check valve can cause the steer cylinder to wander under load, directly affecting machine control. Replacing it with a correctly rated OEM valve restores full steering response.
- Safety-Critical Hydraulic Function — On aerial boom lifts, uncontrolled steer cylinder movement at height is a serious operational hazard. This valve is a key component in maintaining safe, controlled machine travel and positioning.
A check valve is a one-way hydraulic device that allows fluid to flow freely in one direction while blocking reverse flow when pressure drops or the circuit is inactive. In the steering system of Genie boom lifts, this valve holds the right front steer cylinder stationary whenever the operator is not actively steering, preventing the front axle from drifting due to ground reaction forces or hydraulic pressure loss. When this valve wears or fails, the steer cylinder can creep or shift unexpectedly, causing the machine to track off-line during travel — a condition that becomes especially hazardous when the boom is elevated and the machine is repositioning on site.
