Proportional Pressure Compensated Valve 101057GT / 101057 – Optimized Product Page Content

🔹 Product Overview
The Proportional Pressure Compensated Valve with part numbers 101057GT and 101057 is a highly sophisticated electro-hydraulic component used in the control systems of various Genie Aerial Work Platforms (AWP). This component combines two advanced hydraulic functions:
- Proportional Control: Allows the flow rate (and thus the speed of a function) to be continuously varied and precisely controlled in proportion to the electrical current applied to its solenoid.
- Pressure Compensation: Ensures the flow rate set by the proportional solenoid remains nearly constant, regardless of changes in the system load or pressure.
This valve is essential for achieving smooth, precise, and highly stable variable-speed movements in critical, load-dependent functions (e.g., boom telescope, main lift, or drive). The part number 101057GT is the necessary replacement for addressing issues such as the loss of variable speed control, erratic/jerky function movement under load change, or the inability to maintain a constant speed when climbing or lowering.
🔹 Key Features & Benefits
✅ Proportional Control: Enables smooth, variable speed/force control for fine movement modulation.
✅ Pressure Compensation: Guarantees stable function speed, eliminating speed fluctuations caused by varying loads or system pressure changes.
✅ High Control Fidelity: Essential for critical, load-dependent functions that require the highest level of stability and precision.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 101057GT and 101057.
