| Applications: | The flanged steam ball valves are steel stop valves intended to be used to fully close or fully open the flow of the medium conveyed. The steam ball valves with flanges can not be used for flow throttle or flow control purposes. Special types of these ball valves have been developed for flow control purposes. Owing to their features, the steam ball valves can satisfy the duty of a shutting element in any heating plant system |
