The material surface needs to be hardened, such as by nitriding or ceramic spraying, to improve wear resistance and extend the service life of the sealing surface.
A three-way ball valve is a specialized type of quarter-turn valve designed to manage the direction, distribution, and mixing of fluid flow within a piping system.
Top-entry ball valves are engineered for critical applications where reliability, serviceability, and long-term sealing integrity are non-negotiable.
The DBB double ball valve is an important valve used in pipeline systems for sealing, isolating, and releasing fluid media. Its unique design makes it perform exceptionally well in harsh conditions such as high pressure, high temperature, and corrosive me
Cast steel fixed hard seal ball valves, with their superior sealing reliability and structural stability, have become core equipment in the field of high-temperature media transportation.
Polishing or coating the inner wall of the valve body can further reduce surface roughness, allowing fluid to flow smoothly along the wall.
