High Flow Line Valve - tied diaphragm double seal
Key advantages
  • Combined soft and metal seat design with low permeation rate.
  • Welded diaphragms provide a high leak tightness integrity
  • Tied diaphragm design which minimizes gas wetted volume to allow easy purging.
  • No moving components in the gas wetted area to not generate particles.
  • Secondary sealing to prevent the gas coming in contact with actuator in the case of diaphragm failure.
  • Threaded weep hole for leak test and pipe away connection (M4 thread), allows the connection to a leak detector.
  • Front and back panel valve fixation
