Telescopes

Service valves are operated via ECO-Telescopes with cold forged 12 to 14 mm square rods. Gate valves are operated via ECO-Telescopes with 27 to 32 mm operational elements of malleable cast iron. The spindle extension is extraction secured against forces up to 800 N. Centring caps for service valve telescopes have a diameter of 71 mm, while those for gate valves have a diameter of 80 mm. The inner diameter of the bell tube is 80 mm.

Alternative to our standard hot dip galvanised structural steel ST37-2 or corrosion-proof stainless steel V2A (1.4301 = Cr/Ni-Steel), all telescopes are also available in corrosion- and acid-proof stainless steel V4A (1.4401 = Cr/Ni/Mo-Steel) on request.
