The Genie 69873GT is a genuine OEM Check Valve ED designed to keep brakes released in the event of a temporary loss of charge pressure on Genie GR vertical mast lifts, S and SX telescopic boom lifts, and Z articulating boom lifts. As a direct OEM replacement, this valve is manufactured to the same specification as the original component installed at the factory, ensuring proper hydraulic brake function is restored without guesswork. Cross-reference part number 69873GT against your parts manual to confirm fitment before ordering. Compatible models include the GR-8, GR-12, GR-15, S-60, S-65, S-80, S-85, S-100, S-100HD, S-105, S-120, S-120HD, S-125, S-3200, S-3800, SX-105 XC, SX-125 XC, SX-135 XC, Z-60/34, Z-80/60, and Z-135/70.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the original pressure-response specification so the valve opens and closes at the correct charge-pressure threshold, protecting brake release function.
- Direct Bolt-In Replacement — Matches the original port sizing and thread configuration, allowing this valve to swap in without hydraulic line modifications.
- Broad Fleet Coverage — Fits Genie GR vertical mast lifts, S and SX telescopic boom lifts, and Z articulating boom lifts, making it a practical stocking part for mixed Genie fleets.
- Protects Brake Release Under Pressure Loss — This valve is specifically engineered to hold brakes in the released position during temporary charge-pressure drops, preventing unexpected brake engagement during operation.
- Critical Safety Function — On aerial boom lifts, unintended brake application during travel or positioning can create hazardous conditions; a correctly functioning check valve ensures predictable, controlled machine behavior at height.
A check valve is a one-way hydraulic valve that allows fluid to flow freely in a single direction while blocking reverse flow. In this application, the Check Valve ED holds residual hydraulic pressure at the brake circuit so the brakes remain released even if charge pressure momentarily drops — for example, during a brief pump interruption. Without a properly functioning valve, the brakes could apply unexpectedly while the machine is in motion or elevated, creating an unsafe and uncontrolled situation. When the valve wears, sticks, or fails to seat correctly, operators may notice erratic braking behavior or the machine becoming difficult to drive, both clear indicators that the component needs immediate replacement.
