Following last year's launch of large dimension gate valves series 06/30 in DN 450/500/600, we can now also present an addition to the range of telescopic extension spindles for these main gate valves.
This new range is made with a bottom adapter for a round spindle/key-way in either Ø30 or Ø40 mm –available only in a telescopic version with operation square of 23-32 mm. The length variants (4 different) can be found in the attached updated datasheet and are unchanged compared to the existing extension spindles.
The Ø 30 mm extension spindle is designed for series 55 Power Saver valves. For standard series 55/30 valves a gearbox or electrical actuator should be used.
The Ø 40 mm extension is designed for series 06 DN 450/500/600.
Features:
Please note that the AVK extension spindles now features the below mentioned selling points which range among the highest in both quality and design.
Top operating square and bottom adapter in casted stainless steel.
Inside tubes in hot dip galvanised steel grade 52.
Outside plastic parts in PE with high flexibility and impact strength.
No weldings on internal parts providing high corrosion protection.
Fixatin "ears" placed on the top of the extension for connection to the AVK street covers.
