The tried and tested butterfly valve for large nominal sizes and pressure ratings

The used for many years,our butterfly valves cover with nominal sizes between DN 700 and 3600 and pressure ratings from PN 10 to PN 40 a wide range of applications. Proven details ensure reliable quality and a high degree of cost-effectiveness:

Drive shaft and bearing pin are supported in maintenance-free, self-lubricating plain bearings and hence are highly resilient

Connection between drive shaft and valve disc with proved and robust key connection for force transmission without play even under the highest stresses

Main seal through profile ring that is clamped onto the valve disc and fixed with a clamping ring

Double-eccentrically supported valve disc with optimised flow performance

Sliding crank mechanism with optimal movement kinematics which is almost exactly corresponding to the valve’s characteristic curve (from DN 800 spindle gear up)
