Metal hard sealed ball valve

Metal hard sealed ball valve - adopts a fully metal sealing structure, with a specially hardened sealing surface, suitable for high temperature and high pressure, granular media, long life, high wear resistance, and zero leakage requirements. 1. The hardening treatment of the sealing surface is carried out according to the actual working conditions, and the ball and valve seat are hardened by spraying tungsten carbide, chromium carbide or Stellite alloy to meet the special requirements of high temperature and high pressure, granular medium, and high wear resistance. 2. The sealing level is high, and the sealing performance is guaranteed through a spring-loaded pre tensioning structure and special grinding process - up to ANSI VI standard. Bidirectional sealing structure, no flow direction requirement. 3. The long-life hardened sealing surface can ensure long-term sealing performance.
