Counterbalance Valve 121762GT / 121762 (1000 ATM) – Optimized Product Page Content
🔹 Product Overview
The Counterbalance Valve with Genie part numbers 121762GT and 121762 is a critical, safety-focused hydraulic component used on various Genie Aerial Work Platforms (AWP). A counterbalance valve’s core function is to safely lock a hydraulic cylinder in position and to smoothly control the speed of a lowering or resisting load driven by gravity. This prevents uncontrolled movement or “runaway” of the boom or platform. This specific valve is calibrated with a pressure setting described as 1000 ATM (Atmospheres). While hydraulic pressure is typically measured in PSI or bar/kPa, the 1000 ATM designation indicates a high-pressure setting (approximately 14,700 PSI) for extremely demanding or specialized circuits. (Note: Customers must confirm this high-pressure rating is correct for their machine or if “ATM” is a typo/misnomer for a common pressure unit like PSI or bar in their manual.) Assuming the part number is correct:
This valve is essential for ensuring that critical lift, boom, or extension cylinders operate safely and smoothly when lowering under load. The part number 121762GT is the necessary replacement for addressing dangerous issues such as uncontrolled component descent, cylinder drift, or jerky, erratic lowering movements.
🔹 Key Features & Benefits
✅ Load Holding Safety: Locks the cylinder in position, preventing load drift and unintended movement.
✅ Smooth Motion Control: Controls the speed of lowering/retracting loads driven by gravity, preventing runaway.
✅ High-Pressure Rating: Specified for extremely high-pressure, critical load-holding circuits (1000 ATM nominal setting).
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 121762GT and 121762.
