Angle Seat Control Valve 7020

Transcription

1 Angle Seat Control Valve 72 DN 8 up to DN 8 PN 4 Pneumatically operated control valves for neutral through to highly aggressive media. Integrated positioner Compact design All parts contacting the fluid made from stainless steel Temperatures up to 2 C Working up to 4 bar Type 72 with i/p-positioner Control valve with integrated micropro-cessor-positioner for the control of neutral through to aggressive media in process engineering, chemical industry and for plant equipment. Space saving design and low weight No steady- state air consumption Operation independent of mounting position and supply variations Not sensitive to vibration Instrument grade air not essential Software configurable flow characteristics Protection Class IP65 Technical Information Body material Stainless steel Nominal sizes DN 8 up to DN 8 Connections Pipe thread acc. ISO DN 8 up to DN 8 NPT thread DN 8 up to DN 8 Welding ends DN15 up to DN 65 Nominal PN4 Fluid temperature* -3 C up to +2 C Ambient temperature** -15 C up to +8 C *: Please consider further temperature versions and limits in technical bulletin 32 **: Please consider the limitation of use of the positioner Type 72 with digital positioner Type 849 Optionen e.g.: - Optical position indicator - External I/P-converter Type Ex-electropneumatic positioner ( II 2 G EEx ib IIC T6) Schubert & Salzer Control Systems GmbH, Bunsenstr. 38, 8551 Ingolstadt, Tel: +49 () , Fax: +49 () info.cs@schubert-salzer.com,
