The Premium butterfly valve as a logical and consistent development of butterfly valves that have been tried and tested for many years stands for highest quality in the nominal sizes DN 80 to 600. Perfect solutions ensure outstanding product properties with respect to operating safety, durability and cost effectiveness:
Polygon shaft-hub connection between shaft and valve disc with shut valve eye and 20 % more torque reserves.
Safe sealing using a rolled up, solid seat ring made of stainless steel or in the enamelled version, it sits directly on the smooth vitreous enamel.
Fully rubberised EPDM clamping ring which simultaneously serves as a sealing element, can be easily readjusted and, if necessary, can be easily replaced at any time.
Encapsulated and therefore not touched by the medium shafts
Double-eccentrically supported valve disc with optimised flow performance.
Slider crank mechanism with optimal movement kinematics which corresponds almost exactly to the characteristic curve of the valve
DIN EN 558 basic line 14; optional face-to-face dimension basic line 15 and bypass DN 400 to DN 600
