Abstract: A sanitary valve system (10) comprising an actuator arrangement (20) in an actuator housing (32) comprising a first piston chamber (30I) with a first piston (32I) separating the first piston chamber in a first upper cavity (341U) and a first lower cavity (341L) and having a first piston shaft (36I) configured to operate outside of the actuator housing. The valve system is configured to operate in multiple states. The operation of each state and transitions amongst states including identical states are controlled by regulating the liquid pressure or flow in each respective first and second upper and lower cavities. The regulation of liquid may be via a common distribution plate arrangement (90). The distribution arrangement may be with least one common distribution plate (92) with a set of canals (94) configured to connect at least one set of upper and lower regulation lines (82IU, 82IL,82IIU, 82IIL) with the respective first and second upper and communication lines (50IU, 50IL, 50IIU, 50I IL).

Abstract: A sanitary valve system having a sanitary valve in a valve housing with at least one inlet and at least one outlet, the sanitary valve having at least one surface formed of a hygienic material that prevents growth of bacteria or fungus and is configured to control a flow from the inlet to the outlet by means of a valve regulating element.
