The direct-acting rocker solenoid valve, Type 6606 (2/2- and 3/2-way), Envelope Dimensions [mm] (see datasheet for details)
has minimal dead volume and low-gap, plus an easy to wash inside con-
tour. The medium is exposed only to the housing material and the seal.
The heat transfer into the medium is minimal, since the housing is also Flange connection UNF connection
separated from the coil by a stainless steel plate. The valve is particularly
suitable for dosing, filling, mixing and dispensing small quantities of cor-
rosive medium optimal. C
