single seat valves are used for the universal shut-off of branched pipelines. Due to the combination of several valves, a leakage-proof process management is possible. According to application, you can choose the suitable actuator from a modular system of three actuators depending on what capacity is required. Retrofitting to an actuator having a higher capacity is possible without any adapter pieces. The actuators can be changed over either to air to open-spring to close or to spring to open-air to close, simply by turning them. All actuators have the same overall height which allows a trouble-free connection and optimizes considerably the valve manifold connection. Of course, this compact series meets high hygienic standards. The valves are available as corner, T- and change-over valves
