CKD/Japan Xikai proportional solenoid valve

A2-6500 series CKD/Japan Xikai proportional solenoid valve: When customers prepare their own flow controllers, this series of proportional solenoid valves can be selected, providing customers with more system configuration flexibility.

1CKD/Japan Xikai proportional solenoid valveworking principle

1. When using a proportional electromagnet as an electrical mechanical conversion component, the proportional electromagnet converts the input current signal into mechanical signals such as force and displacement, and outputs them to control parameters such as pressure, flow rate, and direction.

2. When using a DC servo motor as an electrical mechanical conversion component, the DC servo motor converts the input electrical signal into rotational speed, and then outputs force and displacement through reduction devices such as screws and nuts and transformation mechanisms, thereby controlling hydraulic parameters.

2、 Product Features

1. High control accuracy: It can continuously and proportionally control the pressure and flow of the hydraulic system, achieve precise control of the position, speed, and force of the actuator, and reduce the impact during pressure changes.

2. Fast response speed: It can quickly respond to input signals and adjust the output pressure and flow rate in a timely manner to meet the dynamic control requirements of the system.

3. Strong reliability: The dynamic iron core and wear-resistant ring adopt an integrated structure, and the guide tube is integrally formed without welding. The dynamic iron core and guide tube are made of highly corrosion-resistant materials, and the brass valve body is made of zinc free brass material, which improves the durability and reliability of the product.

4. CKD proportional valves are suitable for a variety of fluids, including positive pressure specific and positive and negative pressure applications, and can adapt to various fluids such as drinking water, untreated sewage, rainwater, seawater, acid and alkali salt solutions, organic solvents, etc

IIICKD/Japan Xikai proportional solenoid valveSome product maintenance points

1. Daily maintenance

Appearance inspection: Conduct a weekly appearance inspection of the solenoid valve to check for damage, dirt, and foreign objects. At the same time, check whether the solenoid valve wiring is secure to avoid faults caused by poor contact.

Cleaning treatment: Wipe the valve body with a clean cloth every month to avoid using corrosive cleaning agents. For the valve core and seat, compressed air can be used for blowing to keep the channel unobstructed.

Functional testing: Conduct functional testing on the solenoid valve every six months to observe its response speed and reliability.

2. Regular maintenance

Lubrication and maintenance: Lubricate the moving parts of the solenoid valve every quarter, select appropriate lubricating oil, ensure the flexible movement of the valve core, and reduce wear.

Component inspection: Regularly check whether the cylinder or diaphragm is leaking, whether there is any leakage at the connection thread of each gas source, and whether the connection of each signal wire is loose or worn. Check the wear and compression force of the packing, and replace the packing box regularly if necessary. Check the corrosion and wear of the valve body, valve seat, valve core, etc. Check whether the diaphragm or cylinder O-ring in the actuator is aging or cracked, and replace it if necessary.

Air source and hydraulic oil inspection: Regularly inspect the air source and hydraulic oil, regularly drain the filtering device, remove impurities such as air source and hydraulic oil that supply energy, and prevent impurities from blocking the throttle holes and pipelines.

3. Special case handling

Long term disuse: If the solenoid valve is not used for a long time, the manual valve in front of the valve should be closed, the accumulated water in the valve should be cleaned, and the interior and parts should be wiped clean. After blowing with compressed air, it should be stored. When reusing, the condensed water should be completely drained and tested several times. Only after the switch is normal can it be put into use.

Fault repair: When the solenoid valve malfunctions, such as the valve core being stuck by impurities, the impurities can be washed out with clean water; If the sealing surface is damaged, the solenoid valve should be replaced in a timely manner. During maintenance, the valve and actuator are usually removed from the process pipeline together, and precision machined parts such as valve core components, throttle components, valve seats, etc. should be protected to prevent damage.
