Counterbalance Valve 50481GT / 50481 (3500 PSI Load Holding Valve) – Optimized Product Page Content

🔹 Product Overview
The Counterbalance Valve with part numbers 50481GT and 50481 is a crucial, high-specification hydraulic safety component designed for use in the main boom circuits of the Genie Z-45/25J IC (Internal Combustion) Articulating Boom Lift.1 This valve is a load-holding device typically mounted directly onto a critical hydraulic cylinder.2 Its primary function is to lock the cylinder’s position, preventing it from moving or collapsing under the weight of the boom/platform or due to a sudden loss of hydraulic pressure. Critically, this valve is engineered for a 3500 PSI pressure setting.
This counterbalance valve is absolutely essential for the safety, stability, and control of the boom movement. The part number 50481GT is the necessary replacement for addressing dangerous issues such as boom drift, uncontrolled lowering, or jerky, unstable motion in the circuit it controls. A new, correctly rated valve is paramount for operator safety and machine compliance.
