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. Sealing surface hardening treatment

According to the actual working conditions, 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 media, and high wear resistance.

2. High sealing grade

By using a spring-loaded pre tensioning structure and special grinding technology, the sealing performance is guaranteed to meet ANSI VI standards.

Bidirectional sealing structure, no flow direction requirement.

3. Long lifespan

The hardened sealing surface can ensure long-term sealing performance.
