Relief Valve 122302GT / 122302 (270 PSI Low-Pressure) – Optimized Product Page Content

🔹 Product Overview
The Relief Valve with part numbers 122302GT and 122302 is a crucial, low-pressure safety and control component used in the hydraulic manifolds of various Genie Aerial Work Platforms (AWP), particularly large booms and scissor lifts. This cartridge-style relief valve is a precise device that limits the maximum hydraulic pressure within its designated circuit to a factory-set pressure of 270 PSI (Pounds per Square Inch). If pressure attempts to exceed this low threshold, the valve instantly opens to divert fluid, protecting sensitive low-pressure components or regulating the pressure in pilot/charge circuits.
This valve is essential for maintaining the integrity and control of low-pressure control loops, such as pilot control systems or brake release/charge pressure circuits. The part number 122302GT is the necessary replacement for addressing issues such as failure to maintain the correct low pilot pressure (resulting in unresponsive main valve activation) or allowing damaging higher pressures into sensitive components.
🔹 Key Features & Benefits
✅ Low-Pressure Control: Factory-set to limit maximum hydraulic pressure to a low 270 PSI.
✅ Pilot/Control Circuit Critical: Essential for regulating pressure in sensitive control lines and auxiliary circuits.
✅ Broad RT/Boom Fitment: Widely used in models including the Z-80/60, S-40, GS-3384, and GS-5390.1
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 122302GT and 122302.
