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 shutoff and balancing valves. Kombi-F-II and Kombi-F have functions shut-off, presetting and measuring.
- Balancing through stroke limitation with digital pre-setting and visible pre-setting indicator
- Equipped with 2 pressure test cocks for differential pres-sure measurement (DN25...DN400)
- Non rising spindle with EDD (double sealing system)
- Pre-setting isn`t altered when handwheel is turned
- Stroke limitation-screw protected by protection cap
- PTFE-seat sealing
- Spindle made of stainless steel
- Valve body made of corrosion resistant cast iron
- Available in dimensions up to DN400
