The Genie 31798GT is a genuine OEM Check Valve, #8 O-Ring Ports, built for Genie Z-34/22 IC and Z-45/22 MP articulating boom lifts. As a direct OEM replacement, this valve is manufactured to the same specifications as the original, ensuring a correct fit at the #8 O-ring port connections without modification. Sourced directly through the Genie OEM supply chain, part number 31798GT is the right call when you need a verified, like-for-like replacement on these machines.
Key Features
- Genuine OEM Construction — Manufactured to original Genie specifications, with correct body dimensions and port sizing for consistent sealing at #8 O-ring port connections.
- Exact-Port Fit — Designed for #8 O-ring ports, this valve seats and seals correctly without adapters or rework, maintaining the integrity of the port connection.
- Confirmed Fitment — Verified for Genie Z-34/22 IC and Z-45/22 MP articulating boom lifts; cross-reference part number 31798GT against your machine's parts manual before ordering.
- One-Directional Flow Control — A correctly functioning check valve allows fluid to pass in only one direction, preventing backflow that could cause uncontrolled movement or pressure loss in the circuit it serves.
- Operational Safety — On aerial boom lifts, a failed or leaking check valve can compromise controlled positioning and platform stability; replacing a worn valve promptly keeps the machine performing as designed.
A check valve is a one-way flow control component that allows fluid to move through a circuit in a single direction while blocking reverse flow. On articulating boom lifts like the Z-34/22 IC and Z-45/22 MP, check valves are critical to maintaining controlled, predictable movement — a failed valve can allow backflow that leads to unintended drift or loss of pressure in the circuit it serves. Replacing a worn or damaged check valve with the correct OEM part restores proper directional flow control and helps keep the machine operating safely and dependably.
