Metal seat gate valve for drinking water and neutral liquids to max. 70°C

AVK metal seated wedge gate valves are primarily designed for the flow isolation of a length of pipeline or piece of equipment. It uses a ductile iron gate that houses gunmetal rings to ensure a watertight seal. The non-rising stem design ensures the stem thread is adequately lubricated by the water passing through the valve. In essence, the whole internals are water dependent for lubrication, a factor that safeguards the longevity of the valve.

Variant 37/71-001
Connection: Flanged
Material: Ductile iron
DN: DN50 - DN300
PN: PN 16
Closing direction: Clockwise to Close or Clockwise to Open

Features

  • Gunmetal wedge nut with lubricating abilities providing optimum compatibility with stem
  • The face ring which firmly secured to the wedge is machined to a fine surface finish to ensure optimum contact seal with body seat ring
  • Wedge with guides, which ensure uniform closure
  • A large through bore housing for the stem in the wedge prevents stagnant water or impurities
  • Round EPDM Bonnet Gasket fixed in a recess
  • Countersunk and sealed stainless steel bonnet bolts encircled by the Bonnet Gasket
