  Feature


  • Bubble-tight shut off at full pressure rating

  • Seat and disc are the only two valve parts in contact with the medium

  • Superior design for abrasive and erosive media

  • Very low pressure drop

  • Top bushing absorbs side thrust loads

  • Hub seal provided by preloaded contact between flatted seat surface and disc hub area for positive sealing at all disc positions

  • One-piece wafer thin disc stem gives the very minimum to obstruction to flow

  • Field replaceable seat isolates the body and stem from the flow

  • Molded-in O-rings provide flange sealing and eliminate need for gaskets
