Xmbos***2 patented water magnetized toilet fill valve Main features: 1. Working performance: Ceramic& magnet seal core takes place of traditional silicon rubber seal parts, greatly improving the problems like water leaks, water penetration, water fill noise, sealing part malfunctions. The ceramic piece works quite effective against corrosion, acid, high temperature and pressure, which makes the service lifetime much longer. With the technical design, all these merits make this toilet fill valve model the best in the current toilet tank fitting market. 2. Unique characteristic: Water magnetization technology(two pieces of permanent magnets are placed on the water supply hole with poles opposite to each other, when water go through the water supply hole, the macro molecular water flow quickly through the magnets and cut the line of magnet force vertically, under the function of megnet force line, the water is magnetized into micro molecular water, which highly improve the flushing effect of erasing dirts and killing bacteria) 3. Guaranteed service lifetime:over *0 years. (**0, **0~**0, **0 times of effective running) 4. Working pressure range: excellent water fill/ stop under the water pressure between 0.**1Mpa and 1.0Mpa. 5. Water condition: adapted to various water quality, such as tap water, foul water, sea water, etc. 6. Water temperature range: effective long term running in the water between 0~**2°F. 7. Water level control: ceramic& magnet sealing core makes the water level precisely stable under various static/dynamic working pressure, water level ascending precision is always within 1mm. 8. Water supply: stable water supplement ratio. 9. Product patent info: Invention patent# ************6. Specifications: 1. Thread: G1/2", *5/*6" in plastic, G1/2", 3/8" in copper. 2. Universal fit for various toilet tanks. 3. Installation spec: refer to installation drawing file.
