Proportional Valve 84108 / 84108GT (N.C., Priority Style) – Optimized Product Page Content

🔹 Product Overview
The Proportional Solenoid Valve with part numbers 84108 and 84108GT is a highly advanced electro-hydraulic component used in the control systems of various Genie Aerial Work Platforms (AWP). This valve is configured as a Normally Closed (N.C.) Priority Style proportional valve. Unlike simple ON/OFF solenoid valves, proportional valves allow the flow rate or pressure to be modulated in direct proportion to the electrical current supplied to the coil. The Priority Style configuration means the valve prioritizes flow to its controlled circuit, ensuring stable speed/force even if other circuits are simultaneously active or the pump flow is limited.
This valve is essential for achieving smooth, precise, and controlled variable-speed movements in critical functions like drive, lift, or slew. The part number 84108GT is the necessary replacement for addressing issues such as a complete loss of proportional function, jerky/erratic speed control, or the failure of the controlled circuit to maintain stable speed under load.
🔹 Key Features & Benefits
✅ Proportional Control: Enables smooth, variable speed/force control proportional to the electrical input, essential for fine movement control.
✅ Normally Closed (N.C.): Valve is closed (no flow) when the coil is de-energized, acting as a fail-safe or default position.
✅ Priority Style: Ensures stable and consistent performance of the controlled circuit, even when system pressure or flow fluctuates.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 84108GT and 84108.
