Non-metallic sealing seats are limited by materials, and can not be used in high temperature conditions, or in situations containing solid particles, ash and other media. Successful introduction of metal hard seal seats has expanded the service scope of welded ball valves in petroleum, chemical, power, metallurgy, light industry, environmental protection and other industries.
The selection of new materials and the use of a variety of advanced ball and seat hardening technology greatly improve the surface hardness, and has excellent wear resistance, impact resistance.
Special sealing structure design can prevent valve from jamming at high temperature and ensure flexible opening and closing.
Excellent sealing performance, double interruption and discharge function make the valve suitable for most harsh working conditions.
