Features
- Suitable for liquid and gaseous media in industrial applications as well as for water treatment
- The top flange is standardised acc. to EN ISO 5211
- Due to the special seal contour of the liner in the flange area, no separate gasket is required
- Self-lubricating shaft bearings made of PTFE coated metal bushes
- The shaft mounted in bearings provides a stable shaft guide
- The (spline) shaft inside the disc is completely isolated from the working medium
- Replaceable liner for isolating the working medium from body and spindle
- Lenticular shaped disc for good flow capability
- Reduced leakage and corrosion risk as the spindle is not fixed in the disc by grub screws
- The concentric disc allows bi-directional shut-off
- High stability and low weight even for larger diameters
