When it comes to cleanliness in public or corporate restrooms, the “automatic flush valve” system is becoming the new standard that makes usage more convenient, safer, and professional, especially in an era where cleanliness is a matter of importance to everyone.

But many people may still not be sure what an automatic flush valve is and how it is better than a regular push-button system.

✅ What is an automatic flush valve?

Automatic Flush Valve is a toilet flushing device that does not require hand pressing.

It uses an infrared sensor to detect user activity. When the user leaves the sensor area, the system will automatically clean.

There are versions for:

Urinal
Sit-flat toilet

⚠ What are the limitations of the normal press system?

Must touch the equipment (risk of spreading germs)
Some users “refuse to flush” → odor builds up
If used frequently, the device will deteriorate quickly and require frequent repairs.
Dirtiness affects the image of the organization/place.

💡 Compare automatic flush valves vs. conventional push-button systems.
