The Genie 67721GT is a genuine OEM PO Check Valve designed for the TMZ-50/30 trailer-mounted articulating boom lift. Sourced directly from Genie, this part matches the original valve specification installed at the factory, ensuring correct hydraulic circuit behavior right out of the box. Cross-reference part number 67721GT against your TMZ-50/30 parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the exact cracking-pressure and flow-restriction specifications of the original valve, maintaining precise pilot-operated check function throughout the hydraulic circuit.
- Direct Drop-In Replacement — Matches the original port configuration and thread spec of the CKCV-XCN valve, connecting directly to the existing hydraulic manifold with no rework required.
- Confirmed Fitment for the TMZ-50/30 — Verified for the Genie TMZ-50/30 trailer-mounted articulating boom, so you can order with confidence knowing this valve is the correct replacement for that machine.
- Locks Load in Place — A properly functioning pilot-operated check valve holds hydraulic pressure in the circuit when pilot signal is absent, preventing unintended boom drift or cylinder creep under load.
- Safety-Critical Hydraulic Function — On aerial boom lifts, uncontrolled cylinder movement caused by a failed or leaking check valve is a serious operational hazard; replacing a worn valve promptly restores the hydraulic holding integrity the machine depends on.
A pilot-operated check valve — sometimes called a PO check valve — is a hydraulic component that allows free flow in one direction while blocking reverse flow unless an external pilot signal unlocks it. In a boom lift's hydraulic system, this type of valve is typically used to hold cylinders in position when the machine is at rest, preventing the boom or platform from drifting downward under its own weight. When the valve wears, develops internal leakage, or fails entirely, cylinders can lose their holding position — a condition that compromises both machine function and operator safety. Replacing a damaged valve with a genuine OEM unit like the part restores the circuit to its intended behavior.
