Ductile cast iron valves

The most important attributes of ductile cast iron pipeline systems are reliability and economic efficiency, as a result of permanent corrosion resistance. But DÜKER ensures further corrosion protection with a range of coatings. Therefore our valves are available with enamel or epoxy lining and coating.

SOCKET JOINT – SIMPLE AND SAFE

Water, other liquids and gas must be transported safely and without losses to be of use to us. With our non-flanged connection techniques you obtain a safe system.

TYTON SIT PLUS® - THE THRUST-RESISTING AND SAFE CONNECTION

The cost-saving alternative for a cost-efficient laying of pipeline systems for town areas and trunk lines. The basis of TYTON SIT PLUS® is a further development of the proven system Tyton SIT® which converts the non-secured TYTON joint into a tight, anti-thrust TYTON joint. This thrust-resisting joint is internally equipped with a special gasket armed with corrosion-free chromium steel retaining segments vulcanized into the ring. By using this TYTON SIT PLUS® ring the thrust forces are absorbed inside the joint. The system enables the different segments to turn in the area of the shoulder and to adapt themselves to the given pipe tolerances. The wedge-shaped segments lock themselves into the surface of the pipe and transmit the thrust forces into the socket. TYTON SIT PLUS® is available for the nominal diameter range DN 80 – 600 and an operating pressure up to 10/32 bar. While laying, please observe our laying instructions
