Genebre Art2035 Butt Weld Carbon Steel 1-Piece District Heating Ball Valve (PN40)

Genebre Art2035 Reduced Bore Carbon Steel All-Welded Ball Valve

The Genebre Art2035 is a heavy-duty reduced bore carbon steel ball valve designed specifically for district heating and high-temperature pipeline systems. Its monoblock (one-piece) welded construction eliminates body joints and gaskets, providing exceptional strength, leak-tight performance, and long-term reliability in buried, insulated, or difficult-to-access installations.

The valve is manufactured from painted carbon steel DIN St-37 and supplied with extended pipe ends for butt welding, allowing heat to dissipate during installation and protecting the internal seals. A stainless steel ball with PTFE and graphite seats ensures smooth operation, tight shut-off, and long service life across a wide temperature and pressure range.
