Precise temperature control: high density ceramic valve core, temperature control is more precise, refuses to be hot and cold! Rubber sealing ring: Resistance to High temperature, low temperature resistance, high pressure resistance Ceramic shell: considerably reduces friction loss E64 glue: hard and wear resistant Thicker sealing ring: increases the stability High quality ceramic valve core: wear resistance, high temperature resistance, no deformation The environmentally friendly brass casting body has the advantages of forging resistance, corrosion resistance and good formatting that ordinary lower quality copper does not have. The surface adopts advanced galvanoplasty treatment with PVD mirror, the surface is brilliant and wet, long-term use, shiny and new.
