DISCONTINUED-FieldQ Rack and Pinion Actuator
Important: FieldQ QC Control Modules are now obsolete.
The FieldQ actuator is still available, and it can be used with standard controls via the NAMUR adapter plate. Starting in 2019, the FieldQ actuator design was updated. In our documentation, the older design is referred to as Release 1, and the newer version as Release 2.

  • Heavy duty body castings provide maximum protection in the harsh environment of process plant locations.
  • Polyurethane powder coating provides excellent corrosion resistance on housing and end caps.
  • One piece blow-out proof, pressure balanced, pinion allows safe in-field re-configuration from Fail-Close to Fail-Open.
  • The aerospace type alloy 7075 T6 for the pinion, provides the best combination of corrosion resistance, high strength and a lightweight construction as well as providing protection against galvanic corrosion.
  • Precision dual stroke adjustment provides accurate and intuitive end of stroke adjustment for the Open and Closed valve position.
  • Low maintenance bearings for pistons and pinion.
  • Accurately designed and machined components assure a perfect fit and long cycle life.
  • Stainless steel or Deltatone™ coated fasteners.
  • VDI/VDE 3845 (NAMUR) solenoid adapter interface and top accessory interface.
  • Dual ISO 5211 mounting patterns allow low-profile direct mounting to valves.
  • Drive inserts on the valve flange make direct mounting flexible, either for square, flat head, or round with key way stems.
