Key Features
- Genuine OEM Construction — manufactured to Genie's original specification with correct porting, pressure rating, and valve geometry for this application.
- Direct Installation Fit — engineered as a drop-in replacement for the original valve, requiring no adaptation to mount and connect correctly.
- Confirmed Fitment — designed for Genie Z-30/20 N and Z-34/22 IC articulating boom lifts; cross-reference part number 40665GT with your parts manual before ordering.
- Controlled Load Holding — a functioning counterbalance valve prevents uncontrolled movement of the boom under load, keeping operation smooth and predictable.
A counterbalance valve is a load-holding control valve that prevents a boom section from moving unintentionally when a load is suspended or when the machine is in an elevated position. It works by requiring a controlled pilot signal before allowing fluid to flow out of the actuator, so the boom holds its position under load rather than drifting or dropping. When a counterbalance valve wears or fails, the result can be sluggish or erratic boom movement, or in more severe cases, uncontrolled lowering — either of which signals that the valve should be inspected and replaced promptly with the correct OEM part.
