Description

NEC/ATEX/IEC – Non-Incendive or Intrinsically Safe with range of enclosure options

Category:
  • 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.
  • Available with low power Falcon solenoid valve.
  • Solenoid coils integrated within enclosure
  • Choice of factory pre-wired 3 and 4 way Falcon solenoid valves.
  • Solenoid valves with a choice of Cv ratings and coil voltage
