HARTMANN ball valves of the TBV series can be used when stringent safety regulations require double pipeline closure. Designed for these applications, the HARTMANN TBV series combines two complete and independent closure systems (“double ball valves”) in a single enclosure: 0 bubble seals, which can be between closure systems for testing. The compact design contributes to operational reliability and also helps to save space and reduce costs due to reduced material requirements.
