The Genie 107747GT 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 sourced through Genie's authorized parts program, this check valve is built to the exact specifications required by these large-frame articulating booms. Cross-reference part number 107747GT against your machine's parts manual to confirm fitment before ordering. When hydraulic system integrity is critical at height, installing the correct OEM component is the only reliable option.
Key Features
- OEM-Calibrated Cracking Pressure — Factory-set at 5 PSI, this check valve opens and closes at the precise threshold engineered for the Z-135/70 and ZX-135/70 hydraulic circuits — no guesswork, no pressure mismatch.
- Direct Hydraulic Line Replacement — Engineered to connect directly into the existing hydraulic plumbing on these articulating booms, with OEM port sizing and thread spec for a straightforward swap.
- Confirmed Fitment for Z-Series Large-Frame Booms — Built specifically for the Z-135/70 and ZX-135/70, Genie's largest articulating boom lift platforms, so you can order with confidence.
- Protects Hydraulic Circuit Integrity — A correctly functioning check valve prevents backflow and pressure bleed-down in the hydraulic system, keeping boom functions responsive and controlled under load.
- Critical Safety Component for Elevated Operations — On large articulating booms operating at significant heights, hydraulic valve integrity directly affects boom stability and controlled movement — OEM spec matters here.
A check valve is a one-way flow control device in the hydraulic system, allowing fluid to move in a single direction while blocking reverse flow. On articulating boom lifts like the Z-135/70 and ZX-135/70, check valves protect specific circuits from pressure loss or unintended movement — particularly important when the boom is extended and the platform is elevated. When a check valve fails or begins to bypass fluid, operators may notice slow boom drift, sluggish or inconsistent function response, or an inability to hold position under load — all conditions that demand immediate attention on aerial equipment of this size.
