Burkert Type 6626 combines the reliable and success- ful Rocker principle with a highly innovative new actuator. The TwinPower concept of this actuator reduces the size greatly without loss in performance. Hence the 16 mm wide medium isolated rocker valve, 6626, with a 3.0 mm ori ce and a pressure resistance of 2 bar, provides the same performance as a traditional 22 mm valve. In addition, the inte- grated power reduction decreases the energy consumption by 75%. In combination with other design features the heat transfer into the medium can be reduced to a minimum.
