Telescopic extension spindle for gate valves DN450-600, with break zone in key adaptor #23-32. For water, neutral liquids and gas

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 and a lock spring prevents the telescopic part from collapsing during installation. The extension spindles are made of corrosion-free materials and the centre sleeve and bottom cover protect against penetration of impurities. The design with break zone in key adaptor prevents damage of the valve.

Variant 04/F-017
Material: Polyethylene (PE)
DN: DN450 - DN600

Features

  • The break zone prevents damage of the valve. If a too high torque is applied, the break nut in the key adaptor is easily replaced. Operation is still possible until spare part is mounted
  • The conical key adaptor fits most standard T-keys
  • 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 adapter for maximum strength
  • The bottom cover protects the valve spindle from sand and dirt and enables it to rotate freely
  • Available in different lengths,  L8 = Actual length
