The first soft-sealing butterfly valve with 3 optimised disc designs means less turbulent flow.
DN 20 TO DN 50 – SINGLE SHAFT DESIGN
- Lower friction and pressure losses for optimised Kvs values.
- Optimised disc design means less turbulence and a shorter outlet section – just 2 x DN – downstream of the valve.
- Less turbulence also has the advantage of less noise and vibration in the system.
- Less dirt deposits.
DN 65 TO DN 200 – INNOVATIVE CURVED DESIGN
- Lower friction and pressure losses for optimised Kvs values.
- Optimised disc design means less turbulence and a shorter outlet section – just 2 x DN – downstream of the valve.
- Less turbulence also has the advantage of less noise and vibration in the system.
- Less dirt deposits.
- The curved design is protected by a utility model and as such is unique worldwide.
- The curved design results in increased stiffness and adds stability to the entire shaft-and-disc structure.
DN 250 TO DN 600 – INNOVATIVE HEXO HONEYCOMB DISC DESIGN
- The HEXO honeycomb disc design is protected by a utility model and as such is unique worldwide.
- Lower friction and pressure losses for optimised Kvs values.
- Optimised disc contour means less turbulence and a shorter outlet section – just 2 x DN – downstream of the valve.
- Less turbulence also has the advantage of less noise and vibration in the system.
- Less dirt deposits.
- Weight advantage of the new disc design simplifies handling in the system.
- The HEXO design results in increased stiffness and adds stability to the entire shaft-and-disc structure.
For significant optimisation and a flow with less turbulence and vibration.

Polygonal Shaft-Disc Connection
INNOVATIVE & FORM-FITTING
The connection between the shaft and the disc is designed as a form-fitting polygon for optimum torque transmission. The disc and liner are simple to replace because the polygon is self-centring and no additional fixing pin is required. A flat surface ensures the discharging of air when the shaft is inserted into the disc, for even easier installation.
BENEFITS FOR YOU
- New polygonal connection guarantees maximum reliability.
- Designed as a form-fitting polygon for optimum torque transmission.
- Design rules out any notching effect.
- Easy servicing because the liner and disc are simple to replace.
