Description
Differential Sensing Valve 27804GT / 27804 – Optimized Product Page Content
🔹 Product Overview
The Differential Sensing Valve with Genie part numbers 27804GT and 27804 is a specialized component used in the hydraulic systems of various Genie Aerial Work Platforms (AWP). This type of valve is a key part of hydraulic control systems designed to maintain consistent speed and predictable operation by responding to pressure differences (differential pressure) within the circuit. It often functions as a flow compensator or pressure regulator that automatically adjusts to ensure the priority or speed of one function remains stable, regardless of simultaneous load changes or pressure drops elsewhere in the system.
This valve is essential for achieving simultaneous, smooth, and controlled movement in machines where multiple hydraulic functions may be activated at once. The part number 27804GT is the necessary replacement for addressing issues such as loss of control during multi-function operation, erratic speed changes, or function creep due to the valve failing to accurately sense or compensate for pressure differentials.
🔹 Key Features & Benefits
✅ Pressure Compensation: Automatically adjusts flow to maintain stable performance despite system pressure fluctuations or load changes.
✅ Differential Sensing: Uses pressure differences to regulate flow, ensuring smooth simultaneous operation of multiple functions.
✅ Consistent Speed: Critical for maintaining the predictable speed and control of primary hydraulic functions.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 27804GT and 27804.
