KM Series | Metal seated ball valve

Extreme operating conditions with temperatures up to 450°C and pressures up to 420 bar require special sealing technology in ball valves.Standard soft seated ball valves simply aren't ready for this kind of requirements. Their plastic seals would fail. Metal seated ball valves don't have this problem. However, most metal seated ball valves are not available for high pressures and also not available for smooth operation. Now, AS-Schneider is entering this metal seated ball valve arena with the KM Series.

When developing the new KM Series AS-Schneider uses the latest surface and material knowledge combined with comprehensive engineering know-how. The result is a ball valve with zero leakage even under extreme operating conditions with respect to working pressure and temperature – even though a smooth operation is provided.
