VALCO GROUP

SPECIFIC PRODUCTSVALCO GROUP FRANCE : INVOLVED FROM THE BEGINING INTO THE THERMAL AND NUCLEAR POWER PROGRAM

For more than 100 years, VALCO Group France, through its two companies,

MALBRANQUE and SNRI (Brand names were SERSEG and MM), have supplied

Gate, Globe and Check valves worldwide for the thermal Power Stations.

Since 1970 when EDF and the French government launched the nuclear pro-

gram, VALCO Group France, through its two companies, MALBRANQUE and SNRI

(then companies of the group SEREG Schlumberger), have been deeply in-

volved in the development of valves for the nuclear power plants, for both

conventional island as well as some parts of the nuclear island.

Our valves have been delivered to most of nuclear plants and thermal power

stations, on all the continents:

For most of these plants VALCO Group France provides long term services such

as maintenance, obsolescence (replacement of obsolete device), extension and

optimization.

Following the development of the new generation of reactors EPR, VALCO France

has developed new solutions and has been selected to deliver valves solutions

for the conventional island of the Nuclear Power Plant Flamanville 3.
