Sometimes customer ask Verspec team what means by triple offset of triple offset butterfly valve.
Now let’s know what triple offset is:
A Triple Offset Butterfly Valve has 3 separate offsets. Two of the offsets apply to the location of the shaft in respect to the centerline of the bore and the centerline of the disc/seat sealing surfaces. The third offset is the design in the axis of the seat cone angle.
The advantages of Triple Offset Design
1- Unique conical sealing design ensures that the metal sealing components are never in contact until its final degree of closing – this results in repeatable sealing and a vastly extended valve life.
2- Metal-to-Metal sealing ensures bubble tight shut-off, resulting in zero-leakage performance
3- Suitability to harsh media – construction of the valve features no elastomers or materials typically affected by corrosion
4- Geometric design of sealing components provides friction-free stroking throughout the valve. This extends the valve life and allows a lower torque-actuator to be fitted.
5- There are no cavities between sealing components, resulting in no clogging, low maintenance and extended valve life.
Keeping up with the trend has always been one of the tags for DBV Valve since the beginning, despite we have always been taking pride in our products, we were never self-satisfied, we never stopped updating our equipment and we have always kept our eyes on the various needs in the market. https://dbaovalve.com/butterfly-valves/
