The Laufach works offer ductile iron fittings as per EN 545 for pressure pipelines in water supply and sewage systems. A large range of products makes Düker the top address for water suppliers and pipeline constructors with special requirements. A full range of gate and butterfly valves, hydrants, non-slam check valves and plunger valves completes the offer.
