456-DP

dynamischer Kombiblock

Suitable for small to large water volumes. For installation in dual-pipe heating systems for consumers with integrated valve. The dynamic valve range Vario-DP makes hydraulic balancing in single and two family homes an easy and fast job.

Low-noise, adjustable combination block with drain and shut-off feature. Adjustment range 20 to 340 l/h, fully adjustable with standard radiator bleed screw key. With cap to protect against incorrect operation. The patented valve insert with automatic flow limiter automatically limits the water volume adjusted at the valves, independent of pressure variation in the heating system. This means that Vario-DP always supplies the right water volume to the radiator, regardless of the number of open or closed valves in the system. The valve insert can be replaced with the MGV mounting unit at operating pressure without the system having to be drained.
