Water chamber PVK 400/315mm butterfly valve

Drainage well with flap valve for collecting stormwater and drainage water

The Meltex 400/315 drainage well features a flap valve at the inlet, with a height difference of only 20 mm between the inlet and outlet. The outlet is equipped with a water trap. The well includes a 70-liter sediment trap and has a total height of 1500 mm.

The well package includes a standard 315×750 mm telescopic pipe and a 40-ton cast iron cover. The drainage well is also available without the cast iron cover if placed in areas without traffic. In this case, an RST cover or a lightweight plastic cover can be selected.

The primary materials used in the wells and well components are polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC).
