Main advantage of the ceramic disc cartridge:
95%Al2O3 ceramic discs,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.
Alumina ceramic discs properties and application:
Properties of the ceramic disc cartrige: 1) resistance to chemical attack and gas-tight 2) pressure resistant and insensitive to attack by chemical cleaning agents 3) major lime deposits forming at high water temperatures will be removed by the ceramic material. 4) Non-corrosive, high abrasion resistant
Other Application of the ceramic disc cartridge: 1) for titrators 2) for refrigerant valves 3) for analyzers and medical apparatus, medical applications 4) for gas and solids proportion-ing equipment. 5) for espresso and coffee machines 6) ceramic seal and regulator discs for diverters 7) for single-handle mixers 8) for two-handle faucets 9) for sanitary technology 10) for special-purpose valves .
