Application
The Kombi-2-plus is installed in the return mains of pump driven warm water heating systems and cold water cooling systems to regulate the hydronic balance and as shutoff valve. The Kombi-2-plus has an O-ring spindle seal and is maintenance free. The valve body can be insulated easily and is equipped with pressure test cocks for differential pressure or flow measurement.
Further functions can be retrofitted without interrupting operation of the system: draining, filling and automatic regulation (in combination with a Kombi-3-plus BLACK valve in the supply and a Kombi-Diaphragm Unit).
Features
•Maintenance free spindle with double O-ring sealings
•PTFE seat sealing
•High accuracy of the pre-setting because of individual adjustment
•Valve body PN16
•Dimensions DN15 to DN40 can be retrofitted with a Kombi-Diaphragm Unit
•Robust valve body made of corrosion resistant red bronze
•Availabe in sizes up to DN80
•Visible pre-setting dial with concealed pre-setting wheel

NOTE: Differential pressure: Closing pressure for Kombi-2-plus with installed Kombi-Diaphragm Unit. Regarding noise generation the conditions, requirements and installation design have to be taken into account.
Function
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 18 380, VOB part C, is required by national standards.
This requirement is met with the shutoff and balancing valve Kombi-2-plus. The Kombi-2-plus for the return has the functions shutoff, pre-setting, regulation (with diaphragm unit, accessory), draining and filling (draining adapter, accessory).
