Since the control membrane is installed directly in the valve insert and since the valve spindle is used as the pressure sensor, there are no additional control components which might be subject to pollution. The valve operates with a standard valve gasket and does not require additional dirt filters. Images 1 456-DP dynamischer Kombiblock Variants Application 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. Description 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.
