Visit product website DATA SHEET Type 2300 Pneumatically operated 2-way angle seat control valve ELEMENT Type 2301 Pneumatically operated 2-way Globe Control Valve Type 2103 2/2-way diaphragm valve with pneumatic stainless steel actuator (Type ELE- MENT) for decentralised automation Standard | EU | en | 2024 - 03 - 06 | 19 Digital electropneumatic positioner for integrated mounting on process control valves
- Compact and robust stainless steel design Start-up with automatic TUNE function Contact-free position sensor Integrated pilot air duct in the actuator AS interface, IO-Link or Bürkert system bus (büS) Compact positioner for integrated mounting on pneumatically controlled process control valves. The set-point value setting default occurs via standard signal mA and/or via AS interface. A sensor element with contactless function records the valve spindle position. Simple start-up via automatic TUNE function and setting with the aid of DIP switch: Sealing threshold Characteristic selection Inversion of direction Manual/automatic operating state switchover Digital input Additional options available for parametrising using device DTM. A software inter- face can be used for the linearisation of the operating characteristic with the aid of a freely programmable characteristic, amongst other things. The status indicator functions using LEDs. An analogue position feedback can be optionally integrated. Product variants described in the data sheet may differ from the product presentation and description. Type description Can be combined with Type 8694 © Christian Bürkert GmbH & Co.
