Notices

Air Source

  • About Fluid Type

    Compressed air is the preferred fluid. If using other fluids, please contact our company.

  • When Containing Large Amounts of Condensate

    Compressed air containing large amounts of condensate is a common cause of malfunctions in pneumatic equipment. Therefore, please install an air dryer and condensate collector before the filter.

  • Condensate Drainage Management

    If condensate from the filter is not drained, moisture will flow into the secondary side, causing malfunctions in the pneumatic equipment.

    When drainage is difficult, it is recommended to use a filter with an automatic drain device.

  • About Air Types

    When compressed air contains chemicals, organic solvents, synthetic oils, salts, corrosive gases, or other impurities, it will damage the equipment or cause malfunctions. Therefore, please do not use it.

Usage Environment

  • Do not use in environments containing corrosive gases, chemicals, seawater, water, or water vapor.

  • Do not use in locations exposed to direct sunlight.

  • Do not use in locations subject to vibration or impact.

  • Do not use in areas with people or areas radiating heat.

Installation and Debugging

  • Before installation, please confirm the airflow direction.

  • If an audible leak occurs, or the equipment malfunctions, stop using it immediately.

  • Please periodically check for loose piping and leaks.

Maintenance and Inspection

  • Please perform maintenance and inspections according to the order in the instruction manual.

    Improper operation may damage components or devices, or cause malfunctions.

  • Maintenance Operations

    Improper operation of compressed air can be dangerous. Therefore, in addition to strictly adhering to product specifications, filter replacement and other maintenance should be performed by personnel with extensive knowledge and experience in pneumatic equipment.

  • Condensate Drainage

    Please drain condensate from filters and other devices periodically.

  • Pre-maintenance Inspection

    Before disassembling the product, please disconnect the power supply. Additionally, the supply pressure must be turned off and the compressed air in the piping must be purged. Ensure the atmosphere is open before proceeding.

  • Post-maintenance Inspection

    After installation, repair, or modification, reconnect the compressed air and power supply, and then perform appropriate functional and leak checks. If there is an audible leak or the device malfunctions, do not use it and verify that the installation is correct.

  • Disassembly and Modification Prohibited

    Do not disassemble or modify the main unit.

Plain language sourcing guide for SMC check valve with quick-change coupling, AKH04-00

Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.

Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.

Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.

If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.

Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.

Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.

Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.

Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.

For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.

For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.

For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
