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 DIN 18 380, VOB part C, is required by national standards.
This requirement is met with V4 Kombi shutoff and balancing valves. V4 Kombi have functions shut-off, pre-setting and measuring.
