Ball valves are compact and reliable shut-off valves widely in almost all industries. However, under extreme service conditions, conventional soft-seated designs perform not good. Challenging condition such as high-temperature or high pressure fluids, abrasive/corrosive medium, and crystallization-prone substances can rapidly destroy soft sealing surface. Metal-seated ball valves provide an effective solution. Even in the most severe services — including high-pressure/temperature (HPHT) systems, high-frequency cycling, and abrasive slurry transport — ATW's valves can ensure: - Low-friction with consistent torque - Long service life - Reliable internal and external sealing performance
