Product Description
The hydronic balance is a significant requirement for the efficient operation of a hydronic heating or cooling installation.
In an unbalanced system under or over provision of hot water to individual radiators or circuits can occur. Apart from the correct selection of radiator valves, regulation of individual circuits is also necessary and in some cases, such as in DIN 18380, VOB part C, required by national standards. This requirement is met with Kombi-F-II and Kombi-F shut-off and balancing valves. Kombi-F-II and Kombi-F have functions shut-off, presetting and measuring.
