ECO-Telescope
ECO – for service and gate valves
ECO telescopic spindle extensions can be used to operate tapping as well as gate valves between DN 40 and DN 450. ECO-Standard-Telescope as well as ECO-Multi-Telescope are available in special models to be applicable to butterfly and ball valves also. All components used are selected to ensure long-term immaculate and durable function. Experience and quality acquired over the course of decades ensure reliability and longevity.
ECO – coupling sockets
ECO coupling sockets are equipped with a special NIRO bolt by default. It is attached to the coupling socket by a bolt plug and thus tool-free and conveniently available for assembly.
ECO – Duplex-Socket
As an alternative to the default coupling socket, the Duplex-Socket can be provided. It enables tool-free assembly of the spindle extension to the valve by simple plug-on mechanics. Duplex-Sockets are available for valves up to DN 300. Steel bolts in PE-Hulls protect against corrosion and allow for easy disassembly even after long periods of service.
ECO – Dirt disks and bell tubes
ECO dirt discs enclose the telescopic spindle extension and efficiently prevent contamination by sand and dirt from the bottom. For most tapping valves, as well as a variety of gate valves, universal dirt disks may be used. Additionally, a great number of valve specific dirt disks and adaptors are available, ensuring ideal fit to most valve designs.
ECO-Marking-Clip
ECO-Marking-Clips may be mounted conveniently to the top of the telescope. A variety of coloured clips are used to mark different carrier pipes visually. Clips are also available in black and made of magnetic material for easier ranging of ECO-Telescopes using a metal detector.
