XCMG Road Roller The electromagnetic valve 80090291

In a road roller, an electromagnetic valve (also known as a solenoid valve) is a crucial component of the hydraulic system. These valves control the flow of hydraulic fluid to various hydraulic cylinders, motors, or other hydraulic components within the roller. Here's how they work and their importance:

1. Function: Electromagnetic valves are actuated by an electrical signal. When the electrical current is applied, it energizes the solenoid coil, creating a magnetic field. This magnetic field then moves a plunger or armature within the valve, opening or closing the valve ports to allow or block the flow of hydraulic fluid.

2. Control: Electromagnetic valves provide precise control over the hydraulic system. By adjusting the electrical signal sent to the solenoid, operators can regulate the flow of hydraulic fluid, controlling the speed and direction of hydraulic cylinders or motors.

3. Application: In a road roller, electromagnetic valves are used in various hydraulic functions, including controlling the steering system, braking system, vibration system, and other hydraulic-powered components. For example, they may control the flow of hydraulic fluid to adjust the position of the steering cylinders or engage and disengage the vibration mechanism.

4. Reliability: Electromagnetic valves are known for their reliability and fast response times. They can open or close quickly, allowing for precise and efficient control of hydraulic functions in the road roller.

5. Maintenance: Like all hydraulic components, electromagnetic valves require regular inspection and maintenance to ensure proper functioning. This includes checking for leaks, cleaning or replacing Filters, and testing the electrical connections to the solenoid coil.
