Design of high-quality production of slide and wedge-gate stamp-welded valves for enterprises of atomic energy industry, thermal power and oil and gas industry with use of nanostructured protecting coating


Mastering the production of fittings for development of major pipeline transport and Russian Federation atomic energy system, and also for full meet of the demands for slide, wedge-gate stamp-welded valves in the domestic market of TPS and APS and for export deliveries on basis of the use of modern progressive sectoral technologies, which provide high level of reliability, industrial and ecological safety.

Field of application

The use as block devices of high reliability and technical safety for cancellation of actuating medium in pipelines of infrastructure oil trunk line and isolation valve for new blocks of atomic power stations under construction. The use at the most dangerous sections with a purpose of level increase of their security against severe accidents and disasters, which have regional, national and global social, economic and ecological results.

Novelty, advantages
