The EIE story


A French manufacturer

EIE holds a number of patents and designs the key components of the existing or custom-built solutions sold to its customers. Almost all products are manufactured at EIE’s industrial base in the Seine-et-Marne department,  

where the company has large workshops, which accommodate the sheet metal working, manual welding and robotised welding stations. A designated spraying zone complete with spray booth ensures a quality of finish worthy of the automotive industry.  

Production plant

Combining innovation with technical support

EIE is all about providing a reliable service and supporting its customers to ensure the success of their projects, making use of its expertise in these specialist areas in order to offer cost-effective, technically reliable solutions that remain viable over the long term.  

The company’s in-house metal cutting workshop manufactures all the special parts such as custom-made manholes needed for working on water supply networks.  

EIE also supplies all the tooling needed for fountain building, and has developed a wide range of tools to facilitate pipeworks.  

Focus on solutions

3D isolation valve

The 3D isolation valve was designed to isolate a section of pipe to allow repairs to be carried out,  

without having to shut off the water supply to users located between the two valves.  


    The valve can support pressure of up to 10 bar. It resists temperatures of up to 80°C.


    By installing a 3D valve, an operation under full load can be carried out, with no need to shut off the water and perform a purge before resuming service. This would be a costly operation, wasting much water. 


    The 3D valve is a universal concept applicable to all pipe configurations, from ND80 to ND600.
