xmbos-111 is designed to replace diaphragm style fill valve, much more durable and maintenance-free.
1. Longivity of over 300,000~500,000 times of effective running. 
2. Stable water fill under water pressure of 0.01~16bar.
3. Precise water fill level control (water fill stops within 1mm above CL line under pressure of 0.01~16bar).
4. Stable water supply volume (water supply volume hardly varies under low/high pressure).
5. Good adaption to various water quality (Heavy duty ceramic works good against acid/corrosion/high temperature etc).
6. Compact design of height adjustment.
7. Anti-siphon design preventing contamination of fresh water
8. Ultra quiet operation under high/low pressure.

xmbos-212 adopts world-first magnet&gravity double seal technology, magnet force is used to increase the seal reliability and decrease the push force, while the traditional flush valves are sealed only by water gravity.                                                                               
1. Soft push force of only 800g and can be customer-designed.
2. Strong and fast flushing (3.3L/S).
3. Adjustable full/half flush volume.
4. Good adaption to various water quality.   
5. Longivity of over 300,000~500,000 times of effective running.
