Surface boxes cast iron

Surface boxes are required to protect and close off the operating points of underground valves. These surface boxes are labelled to make it easier to identify which fittings belong to the gas, water, district heating and wastewater network and how they work. In addition, surface boxes are used for pipework components that are used for control and measurement purposes, for example.

Additional information can be found at the DVGW and in the DVGW regulations.
