280 PSI Relief Valve 101446GT / 101446 (Low-Pressure Limiting Valve) – Optimized Product Page Content

🔹 Product Overview
The Relief Valve with part numbers 101446GT and 101446 is a crucial, precision hydraulic component used throughout the low-pressure control circuits of various Genie Aerial Work Platforms (AWP). This cartridge-style relief valve is a precise safety device that limits the maximum hydraulic pressure within its designated circuit to a factory-set pressure of 280 PSI (Pounds per Square Inch). If pressure attempts to exceed this very low threshold, the valve instantly opens to divert fluid, protecting sensitive or low-pressure components downstream.
This valve is essential for maintaining the integrity and control of specific low-pressure circuits, such as pilot lines, return lines, or very light-duty auxiliary functions. The part number 101446GT is the necessary replacement for addressing issues such as a failure to hold the correct low pressure (resulting in erratic function of pilot-operated valves) or a complete malfunction that could allow damaging higher pressures into the sensitive low-pressure control circuit. A properly functioning valve with the correct low-pressure setting is critical for system accuracy and safety.
🔹 Key Features & Benefits
✅ System Overload Protection: Factory-set to limit maximum hydraulic pressure to a low 280 PSI.
✅ Pilot/Control Circuit Critical: Essential for regulating pressure in sensitive control lines, ensuring proper function of main valves.
✅ Precision Low-Pressure Integrity: Designed for durability and reliable performance in low-pressure hydraulic circuits.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 101446GT and 101446.
