​EAK DOUBLE-ECCENTRIC BUTTERFLY VALVE

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

The ERHARD EAK range of butterfly valves come in nominal sizes between DN700 and 3600 and pressure ratings from PN10 to PN40, to suit 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 of 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 DN800 spindle gear up).
