The Genie 74136GT is a genuine OEM Check Valve, #8 Port - #6 Male ORS built for Genie articulating and trailer-mounted boom lifts, including the TZ-50/30, TZ-50, and Z-34/22 N. As a genuine OEM part, it is manufactured to the same specification as the original component installed at the factory. Cross-reference part number 74136GT against your machine's parts manual to confirm it is the correct valve for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original specification, with the correct port sizing and thread form to match the mating connections on your machine.
- Correct Port and Thread Configuration — Sized at #8 port with a #6 Male ORS fitting, ensuring a direct connection to the existing fluid line without adaptation or rework.
- Broad Boom Lift Compatibility — Confirmed fit for the TZ-50/30, TZ-50, and Z-34/22 N, covering both trailer-mounted and self-propelled Genie articulating boom models.
- One-Way Flow Control — A check valve permits fluid to flow in only one direction. A worn or failed valve can allow backflow, causing unintended movement or loss of position in the circuit it serves.
- OEM Part Number Assurance — Ordering by part number 74136GT ensures you receive the exact valve Genie specifies for these models, eliminating the guesswork of cross-matching third-party alternatives.
A check valve is a one-way flow control device that allows fluid to pass through in a single direction while blocking reverse flow. It is commonly used to hold a load in position, protect components from backflow pressure, or sequence movement within a circuit. When a check valve wears out or fails internally, fluid can migrate in the wrong direction — causing drift, sluggish response, or loss of control in the circuit it serves. Replacing a failed valve with the correct OEM part restores proper directional flow control and returns the machine to normal operation.
