AVK extension spindles
AVK extension spindles are produced on fully automated state-of-the-art production equipment to ensure a uniform quality. They are made of corrosion resistant materials, and the inner tube is press fit to the top spanner and the bottom adaptor to safeguard the galvanization of the tube. The bottom cover protects the valve spindle from impurities and enables it to rotate freely.
The basic design of the AVK extension spindles for service connection valves are:
- Patented “Safe-click” provides a secure and fast mounting process
- Fixed length extension spindles with patented expanding bolt design feature easy shortening by mere use of a hacksaw
- Telescopic extension spindles facilitate on-site adjustments, and feature a defrosting hole and lugs for fixation to AVK surface boxes and support tiles
- Available for DN25-50 valves and with pipe covers from 0.7 to 3.1 metres
