The Genie 94757GT is a genuine OEM Check Valve, 3 PSI designed for a wide range of Genie telescopic boom lifts, articulating boom lifts, and scissor lifts. As a direct OEM replacement, this valve is built to the same specifications as the original component installed at the factory, ensuring the hydraulic system performs exactly as engineered. This part fits an extensive lineup including S-series telescopic booms such as the S-40, S-60 XC, S-80, S-85, S-100, S-105, S-120, and S-125, articulating boom lifts including the Z-60/34, Z-80/60, Z-135/70, and ZX-135/70, and GS scissor lifts including the GS-3384, GS-3390, GS-4390, and GS-5390. Cross-reference part number 94757GT against your parts manual to confirm the correct application before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to the exact cracking pressure specification of 3 PSI, ensuring the valve opens and closes at the correct threshold for proper hydraulic circuit function.
- Direct-Fit Replacement — Engineered to swap in place of the original component with no rework to hydraulic fittings or adjacent plumbing required.
- Broad Genie Compatibility — Fits Genie S and SX telescopic booms, Z and ZX articulating booms, and GS scissor lifts, covering a large portion of the Genie aerial-lift fleet.
- Prevents Hydraulic Backflow — Maintains one-directional flow in the hydraulic circuit, protecting actuators and cylinders from reverse pressure surges that can cause drift, sluggish response, or component damage.
- Operational Safety on Elevated Platforms — A properly functioning check valve is critical to maintaining controlled boom and lift movement at height; a failed or leaking valve can compromise platform stability and predictable machine response.
A check valve is a one-way flow-control device in the hydraulic system that allows fluid to pass in a single direction while blocking reverse flow. In aerial lift applications, check valves protect hydraulic cylinders from losing pressure when loads are held elevated, helping prevent unintended platform drift and maintaining smooth, controlled movement during operation. When a check valve fails — whether it leaks past its seat or sticks open — the result can be slow or erratic boom movement, cylinder drift under load, and increased wear on other hydraulic components, making timely replacement essential to keeping the machine operating safely and predictably.
