Telescopic extension spindle for gate valves DN40-400, 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.

- 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 centre 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 protects the valve spindle from sand and dirt and enables it to rotate freely
