Pressure independent balancing and control valve (PIBCV)
Designed for modulating control of terminal units in heating and cooling systems, the TBV-CMP ensures optimum performance over a long lifetime. Correct control characteristic contributes to a linear circuit characteristic for accurate hydronic control. The TBV-CMP together with our balancing instruments gives possibility for advanced measuring and diagnostic.
