Proportional Solenoid Valve 27801GT / 27801 – Optimized Product Page Content

🔹 Product Overview
The Proportional Solenoid Valve with Genie part numbers 27801GT and 27801 is a sophisticated electro-hydraulic cartridge used in the precision control manifolds of various Genie Aerial Work Platforms (AWP). Its function is to provide proportional control, meaning it does not merely switch hydraulic flow ON or OFF, but rather modulates the flow rate (speed) of a hydraulic function precisely and continuously in proportion to the variable electrical input signal.
This valve is essential for achieving the smooth, feathered, and variable-speed movement required in critical functions like main boom extension, slew, or drive speed control. The part number 27801GT is the necessary replacement for addressing issues such as loss of fine speed modulation, erratic or jerky movement, or a complete failure of the associated proportional function due to a damaged coil or stuck spool.
🔹 Key Features & Benefits
✅ Proportional Flow Control: Enables smooth, variable speed control (feathering) directly proportional to the electrical input.
✅ Precision Modulation: Essential for functions requiring high control fidelity and smooth start/stop capability.
✅ Solenoid Actuated: Electrically controlled for seamless integration with the machine’s control system.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 27801GT and 27801.
