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.
