BUTTERFLY VALVE WAFER TYPE of carbon steel ( ) series

Transcription

1 Operation WAFER TYPE of carbon steel 1100 ( ) series C ont R o L Operation Edition Wafer type butterfly valve 1100 ( ) series is used in industrial pipelines for demanding on-off and regulating tasks as well as in district heating, district cooling and power production. It is tight to both directions of flow. The body material is cast carbon steel. Double eccentric disc and shaft are stainless steel. The shaft packing box is a combination of graphite rings and O-rings which are possible to tighten while in pipeline and are also replaceable. Nominal dimensions: DN 0-00 Nominal pressure PN5bar Disk seal alternatives Stainless steel (CS) PTFE+C (TS) Closing pressure ( P) DN bar DN bar * Tightness class ISO 50, EN 1-1 RATE B RATE A DN bar DN bar ** Working temperature of liquid media (version for steam also available) Face-to-face length according to ISO C -0 C EN 55-1 Series 0 DIN0 K1 or EN 55-1 Series 5 DIN0 K or EN 55-1 Series 1 DIN0 K +10 C -0 C *** Connection Between neck-type flanges: EN109-1 Type 11, Facing Type B, PN5, PN1, PN10, ANSI CLASS 150. Size of erection gasket in accordance to SFS 7, DIN 90. Safety *) Option with Rate A for stainless steel seat is available. **) Wider temperature range is available. Conform to the requirements of the Council Directive 97//EC on Pressure Equipment, marking: Class: gas, group 1. Explosion-proof design in accordance to ATEX Directive 9/9/EC: group II GD, protection concept EEx na T is available as per special order. ***) For the valves DN00 and higher the design pressure (PN10,PN1,PN5)of flanges on the pipeline must be specified in order.
