Metallic-sealing
ball valves

For unrestricted use even under extreme conditions

Our metal-sealed ball valves enable extended service lives. The spring-loaded sealing system also ensures flexible adjustment of the ball valve. In this way, ATEC ball valves can deliver constant performance even under extreme conditions such as high temperatures or high pressure.
