Features

  • Wedge core in ductile iron, fully encapsulated in drinking water approved EPDM in a 2-step vulcanization process that leaves a very strong rubber-iron bond preventing corrosion underneath the rubber. No iron parts are exposed to the water
  • Wedge shoes integrated in the rubber
  • No hollows or cavities where stagnant water might collect and cause contamination
  • Stem of copper alloy C35330
  • Gland-follower for re-tightening with three main O-rings
  • Round bonnet gasket, fixed in a groove in the bonnet preventing it from being blown out in pressure surges
  • Countersunk and hot melt sealed bonnet bolts in stainless steel, encircled by the bonnet gasket preventing contact with the water
  • Full bore and clear way
  • Low operating torque
  • Epoxy coating acc. to DIN30677 and AVK guidelines, RAL 3000. UV resistant coating on request
