The Genie 107751GT is a genuine OEM Check Valve, 5 PSI designed for Genie Z-135/70 and ZX-135/70 articulating boom lifts. As a direct OEM replacement, this valve meets the original engineering specifications for the hydraulic system on these large-platform booms, ensuring correct cracking pressure and backflow prevention without adaptation. Cross-reference part number 107751GT against your Genie parts manual to confirm this is the right component before ordering. Sourced directly through authorized channels, this part carries the quality assurance that critical hydraulic components on high-reach aerial equipment demand.
Key Features
- OEM-Spec Cracking Pressure — Factory-rated at 5 PSI, this Check Valve opens and closes at the exact pressure threshold the Z-135/70 hydraulic system was engineered around — no guesswork, no over- or under-pressure compromise.
- Direct Hydraulic Line Replacement — Designed to install directly into the existing hydraulic circuit on Z-135/70 and ZX-135/70 booms, matching original port sizing and connection type for a straightforward service swap.
- Targeted Fitment for High-Reach Booms — Built specifically for the Z-135/70 and ZX-135/70 articulating boom lifts, keeping your replacement parts matched to the machine in your fleet.
- Backflow Containment Protects the Function Pump — Prevents reverse hydraulic flow from reaching the function pump, protecting upstream components from pressure spikes and contamination that accelerate pump wear.
- Safety-Critical Hydraulic Integrity — On articulating boom lifts operating at extreme heights, a failed or degraded check valve can cause uncontrolled platform drift or erratic boom response. Using the correct OEM-rated valve maintains the predictable hydraulic behavior these machines require for safe operation.
A check valve is a one-way flow control device in a hydraulic circuit. It allows pressurized fluid to pass through in one direction to actuate a function, then seats shut to stop fluid from flowing back toward the pump when pressure is released. On the Z-135/70 and ZX-135/70 articulating booms, this valve protects the function pump from reverse pressure loads that can cause seal failure, internal scoring, or erratic boom movement. When the valve wears, sticks open, or fails to seat correctly, hydraulic fluid can backflow under load — leading to slow or drifting boom functions and potential damage to the pump assembly.
