Counterbalance Valve 48647GT / 48647 (3500 PSI) – Optimized Product Page Content

Genie Counterbalance Valve 48647GT

🔹 Product Overview

The Counterbalance Valve with Genie part numbers 48647GT and 48647 is a high-pressure, safety-critical hydraulic component used on major lift and extension cylinders of various high-capacity Genie Boom Lifts. This valve is indispensable for safe operation, providing two core functions: 1) it acts as a load-holding valve to hydraulically lock the cylinder in place, preventing boom drift, creep, or collapse; and 2) it smoothly controls the speed of any lowering or retracting load driven by gravity, which prevents uncontrolled, dangerous “runaway” movement. This specific valve is calibrated to a high nominal pressure setting of $3500 \text{ PSI}$ (Pounds per Square Inch).

This component is essential for the safe and predictable operation of the machine’s primary movements. The part number 48647GT is the necessary replacement for addressing dangerous issues such as uncontrolled boom descent or retraction, cylinder drift, or jerky, unstable lowering movements, especially when operating under heavy load at height.

🔹 Key Features & Benefits

✅ High-Pressure Rating: Calibrated to a nominal cracking pressure of $3500 \text{ PSI}$ for high-capacity circuits.

✅ Load Holding Safety: Locks the hydraulic cylinder in position, eliminating drift and unintended movement.

✅ Smooth Motion Control: Controls the speed of overhauling loads, ensuring precise feathering and safe descent.

✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 48647GT and 48647.
