The Genie 20318GT is a genuine OEM Check Valve CP100-2-B-O-005 designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts. As a direct Genie OEM component, this check valve is built to the exact specifications your machine left the factory with, ensuring proper hydraulic system behavior across all listed models. This part fits the S-60, S-100, S-105, S-120, S-125, Z-60/34, and Z-45/22, making it a widely applicable hydraulic service part for Genie boom lift fleets. Cross-reference part number 20318GT against your machine's parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Genie's exact flow and pressure specifications, so the check valve seats, seals, and opens at precisely the threshold your boom's hydraulic circuit requires.
- Drop-In Hydraulic Replacement — Matches the original valve body configuration and port sizing, allowing direct installation into the existing hydraulic circuit without adapters or rework.
- Broad Boom Lift Compatibility — Fits Genie S-series telescopic booms (S-60, S-100, S-105, S-120, S-125) and Z-series articulating booms (Z-60/34, Z-45/22), covering a wide range of fleet equipment.
- Consistent One-Way Flow Control — Maintains correct directional flow in the hydraulic circuit, preventing back-flow that can cause platform drift, erratic boom movement, or slow response under load.
- Platform Safety Dependability — On aerial boom lifts, hydraulic valve integrity is directly tied to safe platform positioning; a correctly functioning check valve helps prevent uncommanded boom movement at height.
A check valve is a one-way hydraulic device that allows fluid to flow freely in one direction while blocking reverse flow. In Genie boom lifts, check valves are used throughout the hydraulic system to hold cylinder positions, protect pumps from back-pressure, and maintain stable platform placement during operation. When a check valve fails — through wear, contamination, or a damaged seat — hydraulic fluid can bypass the valve in the wrong direction, leading to platform drift, sluggish boom response, or loss of hold under load. Replacing a worn or leaking check valve with the correct OEM part restores predictable, safe hydraulic function.
