The actuators have a tough and reliable design and are intended to operate quarter turn valves or any other quarter turn application. The Bettis RPE-series comes with coated body and endcaps, has a special high corrosion resistant aluminum pinion design and has stainless steel fasteners, resulting in a long lasting durable actuator design.

主な特長

  • 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 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.
