Complete solenoid valve kits – The solenoid valve kit is the set of two components: the valve cartridge and the electric coil. Being complete with an electrical component, they can be 12 or 24 volts. They can be found in different points of the tail lift system, among these: in the cylinders, in the control unit, at the control of the stabilizers or hydraulic motors or in specific oil sorting points. They can be 2-way or 3-way or 4-way. By disassembling the valve cartridge after removing the electric coil, it is possible to identify the model at how many ways it is by checking the tip that is extracted from the slot. One way is always on the tip, so if it is a 2-way it means that the second way is on the cylindrical body. A 4-way valve will have 3 oil outlets in the circular body and the fourth in the tip.
