Benefits

  • High operating comfort at no extra charge: position indicator with travel stop and locking device outside the insulation. Valve disc position can be checked at any time.
  • Optimum start-up and throttling due to standard throttling plug up to DN 100 (seat-guided V-port plug optionally available for all valve sizes to meet maximum throttling requirements).
  • When the valve is fully open, the bellows is confined within the valve body, protected from pressure surges.
