Features

  • Disc and stem in one piece
  • Die-forged valve body and bonnet
  • Non-turning, rising stem

  • Throttle disc
  • > DN20 with an integral actuator flange
  • HD2000 valves also available in angle pattern

Design Highlights

  • Body seat: tapered seat welded on integratedly with stellite
    
No pressed in or screwed seat ring, therefore no crevice corrosion or loosening
  • Disc and stem in one piece; up from +570°C with stellited tapered seat

    Damage between disc and stem due to high flowrates is prevented
  • Sealing to the outside only by means of the gland packing
    
No bonnet gasket, therefore reduction of possible leakage areas
  • Body and bonnet in two separate pieces with bolted bonnet

    To ease maintenance work, e.g. regrinding of the body seats
  • Yoke sleeve made of bronze
    
Good emergency running properties
  • Cup springs above the upper needle bearing
    To maintain the necessary closing forces when dimensions change between stem and yoke arm due to thermal fluctuation
