AMF3331
The AMF3331 is a 2‑way drain valve with an attached 2‑terminal solenoid coil. It is used on hydraulic liftgate power units to control the lowering of the platform — when energized, the valve opens and allows hydraulic fluid to drain back into the reservoir, enabling a controlled descent. This part is commonly replaced when the liftgate drifts down or fails to lower at the correct speed. The kit includes the valve body and coil, and it replaces the Monarch 707, Anthony A176314, and other equivalent liftgate drain valves.
Designed for hydraulic liftgate pump/reservoir assemblies, not for engine or transmission solenoids. Verify physical dimensions and coil voltage before installation.
