Part number AN374638 is a 12V hydraulic solenoid cartridge valve, a 2-way normally closed poppet valve built for high-precision, high-pressure hydraulic control circuits. When energized, its solenoid coil pulls the internal poppet to open the oil passage; when power cuts off, spring tension resets and closes the circuit to govern the movement of hydraulic cylinders and motors. With high pressure resistance, it installs inside the hydraulic block of farm machinery to manage complex operations such as header folding and height adjustment during harvesting tasks. Full technical specifications are listed on our dedicated parameter page. This aftermarket valve is precision manufactured to withstand heavy field workloads. It fits John Deere large combines, grain and corn headers, cotton pickers and other forage & turf equipment, delivering dependable replacement for your agricultural hydraulic control system maintenance and repair.
