Pneumatic Control Unit for the integrated mounting on process valves

Transcription

1 Pneumatic Control Unit for the integrated mounting on process valves Type 890 can be combined with Compact design Pilot valve with high air flow rate Internal control air channel Optical position indicator Air supply filter Type 00 Angle-seat valve Type 0 Globe valve Type 0 Diaphragm valve Type 000 Angle-seat valve The 890 pneumatic control unit is optimised for integrated mounting on the XX process valve series. Mechanical or inductive limit switches register the position of the valve. The integrated pilot valve controls single or doubleacting actuators. The design of the control unit and the actuator enables an internal control air channel without external tubings. Besides the electrical position feedback signal the status of the device is shown directly on the control head itself. ) The supply pressure has to be 0, - bar above the minimum required pilot pressure for the valve actuator.

2 Ordering information for process valve system with integrated pneumatic control unit A complete process valve system consists of a pneumatic control unit Type 890 and a process valve Type xx or 0xx. The following information is necessary for the selection of a complete system: of the desired pneumatic control unit Type 890 (see Ordering chart on p. ) of the selected process valve Type xx or Type 0xx (see separate datasheet for e.g. Types 00, 0, 0 and 000, 0, 0) You order two components and receive a complete assembled and certified valve. When you click on the orange box "More info." below, you will come to our website for the resp. product where you can download the datasheet.
