Features & Benefits

  • Microprocessor based technology allows digital communication via HART protocol.
  • Remote and local partial stroke test (PST) and emergency shut down (ESD) initiated remotely via HART signal for safety system applications.
  • Optional external button to initiate partial stroke test.
  • Valve position measurement via a non-contact magnetic pick-up eliminates mechanical drive arms or linkages increasing reliability in high cycle applications or where vibration is present.
  • Highly visible position indicator.
  • Models D430 and D431 feature corrosion-resistant resin enclosure.
  • Models D450 and D451 feature heavy duty stainless steel enclosure.
