Classification of CKD solenoid valves CKD solenoid valves are used to control the direction of fluids and are fundamental components of automation, belonging to actuators. They are commonly used in mechanical control and industrial valves to control the direction of the medium, thereby achieving control over the opening and closing of valves. The working principle is that the solenoid valve contains a sealed chamber with different positions having through holes, each connected to different oil pipes. In the center of the chamber is the valve, and on both sides are two electromagnetic coils. When the coil on one side is energized, the valve body is attracted to that side, controlling the movement of the valve body to block or allow different oil discharge holes. The inlet oil hole is always open, allowing hydraulic oil to enter different discharge pipes. Then, the pressure of the oil pushes the piston of the oil cylinder, which in turn drives the piston rod, and the piston rod drives the mechanical device to move. Thus, by controlling the on/off of the electric current through the electromagnetic coils, mechanical motion is controlled.
CKD solenoid valves are divided into three major categories based on their principles:
1. Step-by-step direct-acting solenoid valve: Principle: It is a combination of direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, after being energized, the electromagnetic force directly lifts the pilot valve and the main valve closure in sequence, opening the valve. When the inlet and outlet reach the start-up pressure difference, after being energized, the electromagnetic force operates the pilot valve, and the pressure in the lower chamber of the main valve rises, while the pressure in the upper chamber decreases, utilizing the pressure difference to push the main valve open upwards; when de-energized, the pilot valve uses spring force or medium pressure to push the closure downwards, closing the valve. Characteristics: It can reliably operate at zero pressure difference or vacuum, high pressure, but requires a larger power and must be installed horizontally.
2. Pilot-operated solenoid valve: Principle: When energized, the electromagnetic force opens the pilot hole, and the pressure in the upper chamber drops rapidly, forming a higher pressure below and lower pressure above around the closure. The fluid pressure pushes the closure upwards, opening the valve; when de-energized, the spring force closes the pilot hole, and the inlet pressure quickly forms a higher pressure below and lower pressure above around the closure through the bypass hole, causing the fluid pressure to push the closure downwards, closing the valve. Characteristics: The upper limit of the fluid pressure range is higher, can be installed arbitrarily (customized) but must meet the fluid pressure difference conditions. Solenoid valves are divided into six subcategories based on differences in valve structure and materials: direct-acting diaphragm structure, step-by-step direct-acting diaphragm structure, pilot diaphragm structure, direct-acting piston structure, step-by-step direct-acting piston structure, and pilot piston structure.
3. Direct-acting solenoid valve: Principle: When energized, the electromagnetic coil generates an electromagnetic force that lifts the closure from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closure against the valve seat, closing the valve. Characteristics: It can operate normally at vacuum, negative pressure, and zero pressure, but the diameter is generally not more than 25mm.

1. Cylinders: Used to convert the energy of compressed air into mechanical energy to produce linear motion.
2. Pneumatic valves: Used to control the direction, speed, and pressure of airflow, regulating the operation of pneumatic systems.
3. Pneumatic motors: Devices that convert compressed air into rotary motion.
4. Air tubes and connectors: Used to connect various components in pneumatic systems and transmit air.
Yes, CKD pneumatic components require regular maintenance to ensure normal operation and extend service life. Key maintenance points include:
- Regularly check and replace seals and gaskets to prevent air leakage.
- Inspect and clean filters to ensure clean air quality.
- Lubricate moving parts to reduce wear and improve efficiency.
- Check air tubes and connectors to ensure secure and undamaged connections.
When selecting the appropriate CKD pneumatic components, consider the following factors:
Application requirements: Understand the specific working environment and tasks, such as load, speed, and stroke.
Air source conditions: Ensure that the pressure and flow of the air source meet the component’s requirements.
Installation space: Confirm available space and choose components of suitable size.
Environmental factors: Consider the temperature, humidity, and potential corrosiveness of the working environment to select suitable materials and designs.
Common pneumatic system faults include:
Air leakage: Causes efficiency decline; check seals, connections, and tubes, find leak points, and repair or replace.
Stuck cylinder piston: Possibly caused by dirt or insufficient lubrication; clean the piston and add lubricant.
Valve failure: Check electrical control signals, ensure smooth airflow, and verify if the valve itself is damaged.
Insufficient pressure: Inspect air source pressure, filters, and piping to ensure no blockage or leakage.
