The new compact valves from Bürkert use two different drive and valve concepts, depending on the orifice size: The first is based on linear drive seat valves for orifices DN2 to DN6 (Type 3270: shut-off valve, Type 3280: proportional valve). For the larger orifices DN8 to DN25, the fluid technology specialists from Ingelfingen rely on rotary drive disc valves. They are likewise available as shut-off valves (Type 3275) and as proportional valves (Type 3285). In the seat valves, the direction of flow against the seat is from below.
