BALL VALVE TYPE TBV

Hartmann Valves ball valves of the TBV series are used when high safety requirements require a double line shut-off. For these applications, the Hartmann Valves TBV series designed two complete, independent shut-off systems ("twin ball valve") in just one housing: 0-bubble-tight and testable between the shut-off systems. The compact design creates operational reliability and also helps to save space and costs due to the lower material requirements.
