    Main advantage of the ceramic disc cartridge:

     

    95%Al2O3 ceramic discs are mailly applicated to temperature modulatory valve, conversion valve, modulatory valve of surf and massage bathtub,LPG valves.

     

    Good hermetical, compressive resistance, flexual resistance, using longevity will be above 500 thousand times.
