TBV-C – NPT threads

Terminal balancing valve for ON-OFF control

Designed for use in terminal units in heating and cooling systems, the TBV-C ensures accurate hydronic control and optimum throughput over a long lifetime. IMI Hydronic Engineering’s dezincification resistant alloy, AMETAL®, minimises the risk of leakage.

Features & Benefits

Presetting tool

For accurate and easy balancing.

Shut-off function

Ensures straightforward maintenance procedures.

Self-sealing measuring points

For quick and easy measurement.
