Design Highlights

  • Main valve body is one-piece die-forged incorporating the bonnet flange and the guide for the shut-off device
    Die-forged parts, compared with cast steel parts are generally free from porosity and shrink holes. The special of the valve body minimizes the existance of welding seams.
  • Valve body equipped with guiding system
    Compared to parallel slide valve an almost friction free stroke
  • Hard faced seats (app. 35-37 HRC)
    Extremely resistant to wear
  • Full bore, except DN 65/50 and DN 125/100
    No reduction in seat area
  • Hammer head connection between wedge and stem
    The wedges are able to move parallel to the axis of the pipeline within the guiding groove. This protects the stem against bending moments
  • Pressure sealing bonnet
    Best possible sealing function
