CKD/Japan Hikari Digital Electric Air Pressure Reducing Valve

CKD/Japan Hikari Digital Electric Air Pressure Reducing Valve

The following is a product introduction of the CKD digital electric air pressure reducing valve from Japan's Hikari:

Product features

Display and monitoring functions Equipped with a digital display, it can clearly display control status, output pressure values, etc. It can also display error messages and output status, making it convenient for operators to understand the work situation in real time.

-High precision and high responsiveness: The linearity can reach ± 0.3% F.S., the hysteresis is 0.5% F.S., and the responsiveness is only 0.2 seconds. It can quickly and accurately reduce the inlet pressure to the desired outlet pressure and maintain stability.

-Rich and practical functions: with preset input function, the body can save up to 8ch of pressure, and can be switched through external signals; There is also a direct memory function that does not require external input signals, and the secondary pressure can be freely adjusted using the operation keys.

-Compact design and easy installation: The product is designed to be compact, reducing weight by 25% compared to the original, lightweight, and modular. It can be modularly connected to filters, pressure reducing valves, etc., saving installation space and facilitating system integration.

-Good protection performance: The protection structure is equivalent to IF64, equipped with multiple protection circuits such as power reverse protection, switch output reverse protection, switch output load short circuit protection, etc., which can adapt to various complex working environments.

In the field of transportation, it can be used to control the pressure of pneumatic systems in rail transit, automobile manufacturing, etc., to ensure the normal operation of vehicle braking, suspension and other systems.

In the field of metallurgy, precise control of the pressure of pneumatic equipment during metal smelting and processing can help improve production efficiency and product quality.

Electrical field: pneumatic control systems used for various electrical equipment to ensure reliable operation of the equipment under different working conditions.

CKD/Japan Hikari Digital Electric Air Pressure Reducing Valve

routine maintenance

Pressure management: Check whether the pressure of the compressed air supplied is the set pressure, and whether the pressure gauge indicates normally when the device is in operation.

Air pressure filter management: Confirm whether the condensed water is discharged normally, and check the pollution status of the oil cup and filter element.

Leakage management: Check for compressed air leaks in the piping connections, especially in the movable parts.

Action status management: Pay attention to whether the pressure reducing valve is moving slowly and whether the exhaust status is normal.

Air pressure regulator management: Confirm whether the air pressure regulator operates smoothly, whether the terminal stop state is normal, and whether the connection part with the load is normal.

regular maintenance

Cleaning: Conduct a regular inspection once a year to confirm if the operation is normal. Wipe the outer shell with a dry cloth dipped in diluted neutral solvent, and do not use solvents such as alcohol or cleaning agents that corrode the resin. For pressure reducing valves installed externally, it is also necessary to check whether the valve stem protective sleeve is intact and promptly clean the dust, debris, etc. on it.

Functional inspection: Check the set pressure, response speed, and pressure holding accuracy of the valve once a month. This can be done by smoothly closing the valves on the same pipeline and observing the pressure deviation at the pulse point.

Pipeline cleaning: If the pressure reducing valve is equipped with an external pulse pipeline, it needs to be cleaned every six months. Disconnect the pipeline section where the valve is installed and drain it, remove the pulse pipeline and perform a purge.

Filter cleaning: Based on the pressure difference displayed on the pressure gauge before and after the filter, determine the blockage of the filter and clean the filter installed in front of the valve in a timely manner.

Maintenance precautions

Before maintenance, cut off the power supply, stop supplying compressed air, and confirm that there is no residual pressure before operation. When changing the output setting value, it should be done after the device has stopped running.
