Precise temperature control: high density ceramic valve core, the temperature control is more precise, refuse to be hot and cold Rubber sealing ring: high strength temperature, low temperature resistance, high pressure resistance Ceramic shell: considerably reduces friction loss E64 glue: hard and wear resistant Ring thicker sealing: increases stability High quality ceramic valve core: wear resistance, high temperature resistance, no deformation The brass casting body environmentally friendly has the advantages of forging resistance, corrosion resistance and good shaping that ordinary lower grade copper does not have. The surface adopts advanced PVD mirror electroplating treatment, the surface is bright and wet, long-term use, shiny as new. store wish you a happy life
