    Depending on the version, the seat of the valve is closed with or against the medium flow. Spring force (CFA) or pneumatic control pressure (CFB and CFI) generate the closing force on the swivel plate. The force is trans- ferred via a spindle which is connected to the actuator piston. the exact description of the control functions can be found in the operating manual for type 2000 under: www.burkert.com. 9.1.1 control function a (cfa) In rest position, the valve is closed by spring force. By pressurizing the lower control connection, the seal...
