Features

  • Wedge nut in dezincification resistant brass, designed as a fixed, integral part of the wedge which prevents vibration and ensures durability
  • Wedge and wedge nut fully vulcanized with drinking water approved EPDM
  • Wedge shoes in PA and guide rails on the body make the wedge slide easily up and down, keeping operational torque low even with high differential pressure
  • A large conical stemhole going all the way through the wedge ensures circulation and prevents stagnant water
  • Stem in stainless steel 1.4104 with wedge stop and rolled threads for high strength
  • Full circle thrust collar keeps the stem firmly lined up and ensures low operating torque
  • Triple safety stem seal with a wiper ring outermost to protect against contamination from outside, in the middle four O-rings around the radial bearing and innermost a lip seal as main seal to the system pressure
  • Bonnet gasket with a circular cross-section and fixed in a recess to avoid blow-out
  • Counterbored A2 bonnet bolts, sealed with hot-melt and encircled by the bonnet gasket for maximum corrosion protection
