  • Stem seal with one lower main O-ring backed up by two upper O-rings in a polyamide bearing replaceable under pressure
  • 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 5017
