Hartmann ball valves type TBV

Ball valves type TBV are applicable when strict safety regulations require double pipeline shut off. Designed for these applications, the TBV series valves combine of two complete and independent shut off systems in one housing: fully sealed and verifiable sealing between shut off systems. Compact design facilitates reliability and helps to save space and reduce costs associated with the cost of materials.
