Product details

"Hydraulic valve solenoid coils" refer to the solenoid coils found in hydraulic valves. Solenoid valves are a critical component in hydraulic systems, utilizing electromagnetic force to control fluid flow. The solenoid coil is the core component of the solenoid valve; when current flows through the coil, it generates a magnetic field that interacts with the valve spool's permanent magnet or iron core, causing the spool to move and thereby changing the valve's open or closed state, which in turn controls the direction, pressure, and flow rate of the oil in the hydraulic system.

Here are some specific details about hydraulic valve solenoid coils:

1. Working Principle:

• When the solenoid coil is energized, it generates an electromagnetic field that interacts with the permanent magnet or iron core on the valve spool, causing the spool to move and thereby changing the valve's state.

• When the power is off, the valve spool usually returns to its initial position through a spring or other reset mechanism.

2. Types:

• Depending on the control method, solenoid coils can be classified into direct-acting, pilot-operated, and step-by-step direct-acting types.

• Based on the movement of the valve spool, they can be divided into spool valves and rotary valves.

3. Performance Parameters:

• Operating voltage and current: The operating voltage and current of the coil determine the magnitude of the electromagnetic force generated, which affects the control effect of the valve.

• Response time: The time required from when the coil is energized to when the valve is fully opened or closed.

• Durability: The durability and reliability of the coil are crucial for the long-term stable operation of the solenoid valve.

4. Applications:

• Hydraulic valve solenoid coils are widely used in various hydraulic systems, such as construction machinery, agricultural machinery, automobile manufacturing, aerospace, and other fields.

• They can be used to control the extension and retraction of hydraulic cylinders, the rotation of hydraulic motors, and other actions, enabling various complex mechanical movements.

5. Maintenance and Servicing:

• Regularly check the insulation resistance and connections of the coil to ensure its normal operation.

• Avoid prolonged energization or overheating of the coil to prevent damage.

• When cleaning and replacing damaged coils, ensure the use of products with the same specifications and performance as the original coil.

In summary, hydraulic valve solenoid coils are indispensable components in hydraulic systems, and their stability and reliability are crucial for the operation of the entire system.
