Concealed automatic Urinal Flush Solution

A concealed automatic urinal flush valve uses active infrared automatic sensor technology concealed in the wall. Instead, when you stand in front of the auto flush valve, 2s pre-flush after detection; 6s Flush automatically after leaving. Concealed means the total set is hidden inside the wall or inside the ceramic urinals.

Kege can offer the whole solution, sensor circuit electronic design, infrared sensor eye shape and sizes, valves,control box and power supply design.


  • Automatic on/off: when you stand  in front of the auto flush valve, 2s pre-flush after detection; 6s Flush automatically after leaving
  • Water-saving: Water-efficient faucet reduces overall water usage without sacrificing water.
  • Easily replace the batteries without tools.
  • Power detection. Close the auto flush valve automatically when power failure or low power.
  • Low power indication: This may indicate it is time to replace existing batteries with new ones or there is not enough power going to the unit.
  • Sensor distance adjustable by a remote controller.
  • Healthy and Safe: Touch free, it can prevent the spread of bacteria and germs, convenience and hygiene.
  • Automatically flush if no usage in 24 hours.

Active infrared sensor technology

Active infrared touchless sensors use the emission and reception of infrared beams to detect the presence and/or movement of objects or people in their field of detection. The technology is ideal for applications requiring a long and narrow detection range.

Battery box

Battery box provides power for the sensor and valves working

Automatic urinal flusher uses infrared sensor technology that when you stand in front of urinal ceramic, the sensor detects and gives pulse signal to the solenoid valve to open and give 2s pre-flush, then stop. After you leave, again 6s flush automatically. Program control all the process.

For more details, please visit our blog WHAT IS AUTOMATIC URINAL FLUSH AND HOW DOES IT WORK.

Auto urinal flushers need electricity for sure. Both the sensor and solenoid valve works need electricity power.
Normally three choices:
1.      DC: 4xAA alkaline 6V batteries;
2.      AC: use a transformer to transfer power from 220V/380V to 6V;
3.      DC/AC:Both DC/AC models existed, firstly use AC power to work, if AC no power then DC start to work.

6V with 4xAA alkaline batteries shall last approximately 3000 times/month for one year.
