The filling and Closing Valve Wells are used in the sewerage of draw-off points below the backwater height in air raid shelters.
The tight Valve Well with PE body is light and durable, and ready for installation. The corrosion proof material of the well and the cover (GRP cover Ø 600 mm/0,5t) guarantees a long life span. The valve and the connections are made of cast iron, and are available in sizes DN 70 and DN 100. The connection to the pipe system is done through collar mounting.
