Nominal pressure: CL 150, PN 10, PN 16
Max. nominal size: DN 1000
Max. allowed fluid temperature: 100 °C

Primary seal at the shaft passages:
Ensured by the contact pressure between the valve disc with spherical sealing contour and the elastomer or PFA liner
The compression of the liner's collar between the shaft and the body ensures absolutely tight sealing.
Back-up seal at the shaft passage in accordance with EN 12569:
Ensured by pressing the liner's collar and the backing ring against the shaft
This pressure is applied by means of a tension helical spring.
This back-up seal is not active in normal operation. It is completely independent of the primary seal at the shaft passage.
