Flanged gate valve prepared for post indicator, for fire water applications

AVK series 45/AD gate valves are designed to US-standards, but with European flanges and face-to-face values. Valve body, bonnet and wedge core are made of ductile iron which ensures high strength and reliability. Corrosion protection is excellent with all iron parts coated with fusion bonded epoxy, fasteners in stainless steel and stem in high strength alu-bronze.

Features

  • Fixed, integral wedge nut prevents vibrations in the wedge

  • A large conical stem hole in the wedge ensures circulation and prevents stagnant water from accumulating
  • Stem of high strength alu-bronze C63020
  • Stem seal with an outer wiper ring, two upper O-rings in the radial bearing and one lower O-ring as the main stem seal to the water
  • Round bonnet gasket fixed in a recess to reduce risk of blow-out
  • Bonnet bolts in A4 stainless steel, counterbored, sealed with hot-melt and encircled by the bonnet gasket
  • Full bore and clear way
  • Brass thrust bearing for low operating torque
  • Fusion bonded epoxy coating to DIN 3476, red RAL 3000
