Telescopic extension spindle for double eccentric butterfly valves for water and neutral liquids

AVK telescopic extension spindles are designed for ease of use and long service life. The two fixation lugs can be attached to AVK surface boxes, a lock spring prevents the telescopic part from collapsing during installation, and a defrosting hole enables insertion of a heating element. The extension spindles are made of corrosion-free materials and the centre sleeve and bottom cover protect against penetration of impurities.

Variant 756/7-002
Material: Polyethylene (PE)
DN: DN200 - DN400

Features

  • The conical key adaptor fits most standard T-keys
  • The top adaptor has a defrosting hole intended for insertion of a heating element to prevent freezing of ground water inside
  • The two fixation lugs can be attached to AVK surface boxes and support tiles
  • A lock spring prevents the telescopic part from collapsing during installation, as it creates friction inside the inner square tube
  • The center sleeve protects against penetration of impurities between the two outer PE pipes
  • The inner tube is press fit to the key adaptor and bottom adaptor to safeguard the galvanization of the tube
  • The bottom cover encapsulates the valve garbox input shaft protecting it from sand and dirt and enables it to rotate freely
